Neural Circuits Quotes

In my view, while the single neuron is the basic anatomical and information processing-signaling unit of the brain, it is not capable of generating behaviors and, ultimately, thinking. Instead, the true functional unit of the central nervous system is a population of neurons, or neural ensembles or cell assemblies.

Cognitive neuroscience is entering an exciting era in which new technologies and ideas are making it possible to study the neural basis of cognition, perception, memory and emotion at the level of networks of interacting neurons, the level at which we believe many of the important operations of the brain take place.

Neuroplasticity research showed that the brain changes its very structure with each different activity it performs, perfecting its circuits so it is better suited to the task at hand.

The circadian neurons are one of the few circuits in neurobiology where we have a chance to understand at multiple levels how different sets of neurons communicate with each other - including understanding the wiring rules, the biochemical rules, and the functional behavioral rules.

Mindfulness creates centered awareness. When you do one thing at a time, you're guaranteed excellent results. If you do too many things simultaneously, it messes up your neural circuits. Focus on one thing at a time.

Despite their differences, pride, shame, and guilt all activate similar neural circuits, including the dorsomedial prefrontal cortex, amygdala, insula, and the nucleus accumbens. Interestingly, pride is the most powerful of these emotions at triggering activity in these regions - except in the nucleus accumbens, where guilt and shame win out. This explains why it can be so appealing to heap guilt and shame on ourselves - they're activating the brain's reward center.

All animals exhibit innate behaviors in response to specific sensory stimuli that are likely to result from the activation of developmentally programmed circuits.

I like problems at the borders of disciplines. One of the reasons that neurobiology of learning and memory appeal to me so much was that I liked the idea of bringing biology and psychology together.

[W]hen the martyr's righteous forebrain is exploded by the executioner's bullet and his mind disintegrates, what then? Can we safely assume that all those millions of neural circuits will be reconstituted in an immaterial state, so the conscious mind carries on?

One can, in principle, outline sort of a set of neural circuits that are critically involved and even identify disorders that affect different components of that neural circuit and see what happens if you knock out, for example, inability to recognize faces, how it affects your response to portraiture.

All relationships change the brain - but most important are the intimate bonds that foster or fail us, altering the delicate circuits that shape memories, emotions and that ultimate souvenir, the self.

When we have any function, whether it's language or vision or cognitive functions like memory, we aren't dealing with a straight line to the brain that says 'This is what I do.' The brain builds a network of connections, a network of neurons that have a particular role in that function.

There are no genes or areas in the brain devoted uniquely to reading. Rather, our ability to read represents our brain's protean capacity to learn something outside our repertoire by creating new circuits that connect existing circuits in a different way.

The actual organization of behavior goes on the level of the individual nerve cells and their connections, and we have a hundred billion nerve cells, probably a hundred trillion connections. It's just mind-boggling to think of all the different ways in which they're arranged in a baby's head.

I would argue that if you understand how the cells of the brain are organized into circuits, almost computational circuits if you will, and we see how information flows through those circuits and how it's transformed, we might have a much firmer grasp on why our brains make decisions the way that they do. If we get a handle on that, maybe we can overcome some of our limitations and at the very least we'll understand why we do what we do.
