Neurophysiology Quotes

A child's (or an adult's) nervous system may detect danger or a threat to life when the child enters a new environment or meets a strange person. Cognitively, there is no reason for them to be frightened. But often, even if they understand this, their bodies betray them. Sometimes this betrayal is private; only they are aware that their hearts are beating fast and contracting with such force that they start to sway. For others, the responses are more overt. They may tremble. Their faces may flush, or perspiration may pour from their hands and forehead. Still others may become pale and dizzy and feel precipitously faint. ~ Stephen W. Porges

In other words, dopamine is not about the happiness of reward. It's about the happiness of pursuit of reward that has a decent chance of occurring. ~ Robert M. Sapolsky

If we were designed by engineers, as we consumed more, we'd desire less. But our frequent human tragedy is that the more we consume, the hungrier we get. More and faster and stronger. What was an unexpected pleasure yesterday is what we feel entitled to today, and what won't be enough tomorrow. ~ Robert M. Sapolsky

People into hard sciences, neurophysiology, often ignore a core philosophical question: 'What is the relationship between our unique, inner experience of conscious awareness and material substance?' The answer is: We don't know, and some people are so terrified to say, 'I don't know.' ~ Raymond Moody

Playing nice" comes naturally when our neuroception detects safety and promotes physiological states that support social behavior. However, pro-social behavior will not occur when our neuroception misreads the environmental cues and triggers physiological states that support defensive strategies. After all, "playing nice" is not appropriate or adaptive behavior in dangerous or life-threatening situations. In these situations, humans - like other mammals - react with more primitive neurobiological defense systems. To create relationships, humans must subdue these defensive reactions to engage, attach, and form lasting social bonds. Humans have adaptive neurobehavioral systems for both pro-social and defensive behaviors. ~ Stephen W. Porges

Most 20th century academic physicists, and academia as a whole, simply did not want to touch the subject of consciousness. We have seen psychology grow up, and we've seen the development of neurophysiology and other much more sophisticated science, but only in the recent years have the tools of quantum mechanics been applied to anything representing human scale size. ~ Edgar Mitchell

Synaptic summation is the technical term used in neurophysiology for those instances in which some neuron C is fired only by a combination of neurons A and B. ~ Gregory Bateson

Charles Sherrington, the founder of modern neurophysiology, contended in 1947 that brain processes alone cannot account for the full range of subjective mental phenomena, including conscious free will. "That our being should consist of two fundamental elements offers, I suppose, no greater inherent improbability than that it should rest on one only," he wrote. ~ Jeffrey M. Schwartz

Healthy brains create a healthy society. ~ Abhijit Naskar

In fact, the belief that neurophysiology is even relevant to the functioning of the mind is just hypothesis. Who knows if we're looking at the right aspects of the brain at all. Maybe there are other aspects of the brain that nobody has even dreamt of looking at yet. That's often happened in the history of science. When people say that the mental is the neurophysiological at a higher level, they're being radically unscientific. We know a lot about the mental from a scientific point of view. We have explanatory theories that account for a lot of things. The belief that neurophysiology is implicated in these things could be true, but we have every little evidence for it. So, it's just a kind of hope; look around and you see neurons; maybe they're implicated. ~ Noam Chomsky
