In an article published in 2021, the authors “recorded neurons within the posterior parietal cortex (PPC) of a human . . . participant during actual touch presentation and during a tactile imagery task” (https://doi.org/10.7554/eLilfe.61646). The results of the study showed that PPC neurons that are activated by physical touch are also activated “during a tactile imagery task in a body part-specific manner.” It is a novel finding that suggested “PPC involvement in the cognitive processing of touch [encoding]. . . . cognitive processing prior to active imagery as well as during imagery shares a neuronal substrate with actual touch.” Of particular interest is that the study participant was a tetraplegic in whom touch sensation was tested in insensate parts of the body. Actual touch in those parts was found to elicit no neuronal activation, but imagined touch did activate the known coherent neuronal pathways normally activated by direct touch. Activation was attributed to the cognitive mind through the PPC. The mechanism for the activation was not addressed, but there is accumulating evidence that activation could have been via waveforms generated by the cognitive mind and transmitted encoded through the PPC and its coherent synaptic networks. I propose that the immaterial mind of the study participant accounted for the interpretation of the neural codes as touch, a dualist interaction between immaterial and material entities.

I am offering verses from Psalm 139 that show concordance with points I have shared in my two books and blogs, that God has the power to “translate” neural codes that course through the synaptic networks of our brains as well as to generate them. He knows our thoughts.

You have searched me, Lord, and you know me….you perceive my thoughts from afar….Before a word is on my tongue you, Lord, know it completely….Where can I go from your Spirit? Where can I flee from your presence? If I go up to the heavens, you are there; if I make my bed in the depths, you are there….if I settle on the far side of the sea, even there your hand will guide me….For you created my inmost being; you knit me together in my mother’s womb. I praise you because I am fearfully and wonderfully made; your works are wonderful, I know that full well.

STEPHANIE MARTIN AND COWORKERS PUBLISHED AN ARTICLE IN FRONTIERS IN NEUROENGINEERING, MAY 2014, VOL. 7, ENTITLED “DECODING SPECTROTEMPORAL FEATURES OF OVERT AND COVERT SPEECH FROM THE HUMAN CORTEX.” IN THEIR STUDY SUBJECTS READ THE SAME STORIES BOTH ALOUD AND SILENTLY, OVERT AND COVERT RESPECTIVELY. SPEECH IMAGERY IS INNER SPEECH, SILENT SPEECH, IMAGINED SPEECH, COVERT SPEECH, OR AUDITORY VERBAL IMAGERY. IT IS HAVING WORDS IN THE MIND. IT REFERS TO THE ABILITY TO “HEAR” SPEECH INTERNALLY WITHOUT THE INTENTIONAL MOVEMENT OF ANY BODY PARTS INVOLVED IN GENERATING AUDIBLE SPEECH. THE AUTHORS UTILIZED A METHOD TO “RECONSTRUCT OVERT AND COVERT SPEECH FROM DIRECT INTRACRANIAL RECORDINGS” TAKEN BY ELECTROCARDIOGRAPHY. THEY FIRST BUILT A NEURAL DECODING MODEL FROM SELF-GENERATED OVERT SPEECH, AND THEN [EVALUATED] WHETHER THIS SAME MODEL COULD RECONSTRUCT SPEECH FEATURES IN THE COVERT SPEECH CONDITION.” THEY FOUND THAT “AUDITORY FEATURES OF COVERT SPEECH COULD BE DECODED FROM MODELS TRAINED FROM AN OVERT SPEECH CONDITION, PROVIDING EVIDENCE OF A SHARED NEURAL SUBSTRATE FOR OVERT AND COVERT SPEECH.” THOUGHTS WERE MAPPED TO BRAIN ACTIVITY IN THE FORM OF WAVEFORM TRACINGS THAT WERE DECODED SO THAT BRAIN ELECTRICAL ACTIVITY COULD BE TRANSLATED INTO UNDERSTANDABLE SPEECH. BUT THE PROCESS BY WHICH WAVEFORMS WERE GENERATED THAT WERE REFLECTED IN THE BRAIN TRACINGS WAS NOT ADDRESSED. AND JUST WHAT “HEARS” THE INTERNAL SPEECH? I OFFER THAT IT IS THE IMMATERIAL COGNITIVE MIND IN BOTH INSTANCES, BUT THE AUTHORS PROPOSED THAT “IMAGERY-RELATED BRAIN ACTIVATION COULD RESULT FROM TOP-DOWN INDUCTION MECHANISMS, INCLUDING MEMORY RETRIEVAL AND MOTOR STIMULATION.” THEIR PROPOSAL SUGGESTS A MATERIALIST REDUCTIONISM, ASSIGNING NO ROLE FOR THE IMMATERIAL COGNITIVE MIND.

THE AUTHORS TRANSLATED THE BRAIN TRACINGS USING THE MODEL THEY BUILT, AND IT IS AN ELEGANT STUDY THAT HOLDS ULTIMATE PROMISE FOR BRAIN-COMPUTER INTERFACES THAT CAN MAKE COMMUNICATION POSSIBLE FOR PATIENTS UNABLE TO SPEAK BUT ABLE TO HAVE THOUGHTS. I PROPOSE THAT THEIR STUDY RESULTS POINT TO THE IMMATERIAL MIND AS THE “TRANSLATOR” OF LINGUISTIC NEURAL CODES GENERATED BY BOTH AUDIBLY PERCEIVED AND IMAGINED SPEECH. WE HAVE SEEN IN PREVIOUS BLOG POSTS AND IN MY BOOKS THAT WAVEFORMS ARE TRANSMITTED PROBABILISTICALLY VIA QUANTUM TUNNELING THROUGH POTENTIAL BARRIERS WITHIN SYNAPTIC COMPONENTS TO GENERATE SPIKE TRAINS OF ACTION POTENTIALS TRANSMITTING IN TURN LINGUISTIC NEURAL CODES THROUGH COHERENT SYNAPTIC NETWORKS WITH PURPOSE, SUCH AS TO TRANSMIT SPEECH. I OFFER THAT THE COGNITIVE MIND IS THE GENERATOR OF THE WAVEFORMS AND THE TRANSLATOR/INTERPRETER OF THE LINGUISTIC NEURAL CODES. THAT THE COGNITIVE MIND OF A HUMAN HAS THIS CAPACITY LEADS ONE TO DEDUCE THAT THE MIND OF GOD INDWELLING US AS THE HOLY SPIRIT ALSO HAS THE CAPACITY FOR DUALIST INTERACTION WITH THE MIND AND BRAIN OF MAN.

Today a hymn I sang in my youth came to my mind, “He lives.” Over the past 20 years of my research into interaction between the Holy Spirit and the human spirit and soul I have sought concordance between Scripture and neuroscience concerning this blessed communion restored to repentant mankind by God’s grace. It was made possible by the sin sacrifice of Jesus Christ, resurrected and living. This hymn expresses the findings in song I have shared in my books and blogs. (Thanks to Alfred H. Ackley, 1887-1960)

I serve a risen Savior; He’s in the world today. I know that He is living, whatever men may say. I see His hand of mercy, I hear His voice of cheer. And just the time I need Him He’s always near.

He lives! He lives! Christ Jesus lives today! He walks with me and talks with me along life’s narrow way. He lives! He lives! Salvation to impart! You ask me how I know He lives? He lives within my heart.

In all the world around me I see His loving care. And though my heart grows weary I never will despair. I know that He is leading, thro’ all the stormy blast; The day of His appearing will come at last.

He lives! He lives! Christ Jesus lives today! He walks with me and talks with me along life’s narrow way. He lives! He lives! Salvation to impart! You ask me how I know He lives? He lives within my heart.

Rejoice, rejoice O Christian! Lift up your voice and sing eternal hallelujahs to Jesus Christ, the King! The Hope of all who seek Him, the Help of all who find, none other is so loving, so good and kind.

He lives! He lives! Christ Jesus lives today! He walks with me and talks with me along life’s narrow way. He lives! He lives! Salvation to impart! You ask me how I know He lives? He lives within my heart.

Visual mental imagery refers to the perceptual experience of “seeing in the mind’s eye.” Mario Senden and coworkers published an article in 2019 that addressed the subjective correspondence known between imagined images and physical image perception and further showed that correspondence exists in their neural representations (https://dol.org/10.1007/s00429-019-01828-6). Visual “imagery-based reconstructions of letter shapes are recognizable [by fMRI] and preserve their physical geometry” in the visual cortex. Their results confirmed “that visual mental imagery preserves perceptual topographic organization” in the brain. Images of letters directly perceived by sight were generated via waveforms (photons) transmitted from the letters perceived and transmitted through the retina and optic nerve to the visual cortex. Of great interest in their study is that imagined letters were also detected in visual cortex by fMRI with the same “physical geometry” or topography. This finding suggests that mental imagery by the cognitive immaterial mind also generates waveforms that are transmitted through coherent neural networks to topographically corresponding visual cortex as neural codes. It is the cognitive mind that interprets the codes as perceived, or imagined, imagery. One can reason that the Mind of God has the power to stimulate neural networks to generate images as in dreams and visions?

In support of dualist interactionism I am identifying a lengthy article by Edward Feser that appeared in the American Catholic Philosophical Quarterly, Vol. 87, No. 1, 2013. Its title is “Kripke, Ross, and the Immaterial Aspects of Thought.” Feser cites comments by the materialist philosopher of mind, Jerry Fodor, who stated, “Lots of mental states are conscious, lots of mental states are intentional, and lots of mental processes are rational, and the question does rather suggest itself how anything that is material could be any of these.” One of the authors, the late James Ross, formulated a “powerful argument for the immateriality of our intellectual operations.” (His argument for the immateriality of the intellect was rooted in the Aristotelian-Scholastic tradition.) He identified a contrast between “the determinacy of thought and the indeterminacy of the physical.” Favoring the immateriality of thought is “the contrast between the universality of thought and the particularity of physical processes.” The determinacy of thought was considered by him to be immaterial.

Today in church the speaker emphasized our need to learn to hear the voice of God. I have shared that the indwelling of repentant mankind by the Holy Spirit is a reality today, a reality that did not end with the closure of the biblical Canon as some have believed. I have cited writings of authors who give instruction on how to hear from the Holy Spirit. I have drawn extensively from the literature of neuroscience to explain dualist interaction between the immaterial mind of Man and the material synaptic networks of the brain. Advances in the neurosciences are making dualist interactionism compelling as a process, so that we can be confident that indeed we can be in bidirectional personal communion with the Mind of God through His indwelling Holy Spirit. By the boundless love of God we are offered redemption with the renewal of our souls by the sin sacrifice paid by His Son, Jesus Christ. Upon His resurrection He sent the Holy Spirit as promised before his crucifixion, to live within us as Counselor and Helper. I will continue to post in my blogs findings from the neurosciences that address the “how” of dualist interaction between the Mind of God and the mind of Man. Thank you for your interest.

In my blogs, especially the blog in three parts entitled “Waves in Our Brains,” I have shared how waveforms transmitted through the brain’s neural synaptic networks have amplitude, frequency and shape. Scott R. Cole and Bradley Voytek published an article in Trends in Cognitive Sciences entitled “Brain Oscillations and the Importance of Waveform Shape” (http://dx.dol.org/10.1016/j.tics.2016.12.008) The authors shared that neural oscillations are assumed to have sinusoidal shapes, but in their article they showed “that there are numerous instances in which neural oscillations are nonsinusoidal.” They posit that these features “may provide crucial . . . physiological information related to neural communication, computation, and cognition.

It is remarkable, even inspiring, to realize how our Creator God established the capacity in the brains of humans to process semantic, specified information within neural codes learned over a lifetime, archived in memory and interpreted by the immaterial human mind, created in the Imago dei.

My thesis is that the explanations based on the present materialist/reductionist views on how experiential qualities developed out of inert matter are unconvincing and that an alternate viewpoint offers a more parsimonious and logically coherent account. This is a quotation taken from Leonard Freris’ article entitled “Mind and Matter.” It appeared in Communicative and Integrative Biology in 2014 (http://dx.doi/org/10.4161/cib.26658). He goes on to state that the truth of dualism would support the possibility of the mind surviving the death of the body. “The fundamental problem of Dualism is that it has no convincing explanation of how the two realms of mind and matter interact.” This last statement by Freris underscores the very objective of my studies over the last 20 years, the findings of which are presented in my two books and now in my blogs.

The author asks how experiential phenomena can be physical. The materialist/reductionist agenda is problematic. It is the mind-body problem. He refers to “eliminative materialism” wherein “mental phenomena are considered to be an ‘aspect’ of brain activity,” being physical phenomena. “Cognitive psychology” on the other hand views the brain as a computer. Mental activity is “information processing with experiential activity reduced to a computational process.”

Freris addresses the “mind-body” problem well. He closes with a postscript by Erwin Schrodinger:

But now let us assume that in a particular case you eventually observe several efferent bundles of pulsating currents, which issue from the brain and through long cellular protrusions (motor nerve fibers), are conducted to certain muscles of the arm, which, as a consequence, tends a hesitating, trembling hand to you to bid you farewell - for a long heart rendering separation; at the same time you may find that some other pulsating bundles produce a certain glandular secretion so as to veil the poor sad eye with a crape of tears. But nowhere along this way from the eye through the central organ to the arm muscles and the tear glands - nowhere, you may find, however far physiology advances, will you ever meet the personality, will you ever meet the dire pain, the bewildered worry within this soul, though their reality is to you so certain as though you suffered them yourself - as in actual fact you do!

Deana Vitrano has compared perception and imagination at the visual cortex in a recent article. She presented the findings in her Dickinson College Honors Thesis, Paper 12, in 2012. Her work is consistent with articles that have been presented in the last decade by a number of neuroscientists.

Her study found that imagined patterns and seen patterns produced similar waveforms in 30 college students. Her findings supported “the claim that the visual cortex is activated in a similar manner during both imagination and perception.” That perception and visual mental imagery share common processes in the visual cortex was strengthened by the application of fMRI and PET scans. She recognized the importance of analyzing imagined stimuli that had not been seen before, so that imagined images would not be drawn from memory but were described verbally to the study subject. “The same neural substrates are involved in both imagination and perception.”

Evoked potential waveforms that were recorded were reflective of images that were both perceived and imagined in the “Mind’s Eye.” As I have shared in previous blogs, including “Waves in Our Brains,” Parts 1-3, it can be inferred as the best explanation that the immaterial cognitive mind can generate waveforms that are transmitted through the visual cortex as neural codes that can be interpreted as the images imagined as well as perceived. Her study is consistent with the premise of dualist interaction between the immaterial mind and the material components of the brain’s synaptic networks. That the human mind has been created in the imago Dei infers in a compelling manner that the Mind of God can in fact commune with the mind of Man via the indwelling Holy Spirit, a process supported by the brain’s synaptic networks.
