Analysis of neural computation might have application for deep learning





A new research article, THE THERMODYNAMIC ANALYSIS OF NEURAL COMPUTATION, examines the energy-information cycle of sensory processing in the brain. However, the work has relevance for artificial intelligence, especially deep learning. The cortical brain is an evolutionary marvel which interacts with the outside world via self-regulation, based on its resting or ground state. The resting state, which is disturbed during stimulus and sensory processing, is recovered by automatic operations. 

The brain’s energy need multiplies in the complex brain of warm-blooded animals. Although the human brain represents only 2% of the body weight, it receives 15% of the cardiac output, 20% of total body oxygen consumption and 25% of total body glucose utilization. It is thought that baseline energy consumption has been almost exclusively dedicated to neuronal signaling. This almost constant and huge energy use maintains the brain’s alertness, even during sleep, by an active balance between inhibitory and excitatory neurons. The slightest variation in excitation determines whether a spike is generated. Such a delicate balance of excitatory and inhibitory neurons turns the resting state into a highly energy-requiring state. Even in the absence of stimulus, the equal balance of excitatory and inhibitory neurons produces seemingly arbitrary bursts of resting state’s activation. This is similar to the tennis player moving in place while waiting for a serve. This active balance between contrasting influences ensures the brain’s ability for rapid, targeted response to environmental stimulus. For example, changes in inhibitory neurons increase frequencies and their energetic needs. Via the sensory system, the brain partakes in the energy information exchange with the environment.

Emotions: GPS for your mind




The future is fast approaching and unprecedented technological progress will increasingly characterize every aspect of life. To adapt fluidly to constant changes requires mental flexibility. My upcoming book, 'Emotions: GPS for your mind' anticipates the personal side of this upcoming singularity. My goal is to create a book that serves the reader in every step of the journey. Please join the thousands on this FB platform for discussion and to learn about this paradigm shift. Information and news event about this innovative volume will also be shared on the FaceBook page of the upcoming book. Full of practical information about effective practices based on the latest neuroscience research, this book will put you in the know about this exciting field. The following is an excerpt from the book.

In hierarchic societies of the past, the economic necessity to use brute force and repetitious work made intellect unnecessary and even dangerous. The breathtaking technological transformation of the past one hundred years mostly replaced hard physical labor by machines, whereas the human intellectual involvement is increasingly important at every level in the corporate world and society. The recognition that conflicts and problems between employees tax morale, degrade efficiency and shorten the time spent on work led to increasing awareness and focus on the human side of the work environment. However, because personal behavior originates in the home environment, fruitful change can take generations. Emotional and intellectual patterns are absorbed early in life by observing and copying the family environment. This powerful mental legacy hands the cultural fabric of society to the next generation. Unfortunately, parents also project accumulated fears, weaknesses and imperfect emotional coping mechanisms onto their children. Thus, children grow up with a rigid mindset from the past and carry emotional triggers which predispose them to failure in modern society. Emotional instability leads to attention problems, which make it impossible to absorb the school material and handicap a person’s ability to contribute successfully at work. High intellect requires emotional stability, confidence, and love. 

Starting in Kindergarten, social skills can be taught and practiced in the school. But changing the mind and mastering emotions is possible at any age. Bringing this awareness to companies and communities can transform society.  Over time, the understanding of emotion regulation can become as common as traffic rules. In a world where this understanding is a democratic right, individuals feel secure and supported. This feeling enhances responsibility towards our world, the environment, and for each other. Secure citizenry elects responsible governments, which act for peace, prosperity, and well-being. The positive changes on the individual level would meet positive changes in society and lead to a better world.
