How does experience alter our perceptions? This adapted book excerpt from We Know It When We See It describes how the brain’s visual system rewires itself to make the best use of its neural resources.
Faced with a decision, the brain weighs its options by bundling them into rapidly alternating cycles of brain waves.
The glial cells of the nervous system have been eclipsed in importance by neurons for decades. But glia are turning out to be central to many neurological functions, including pain perception.
The dendritic arms of some human neurons can perform logic operations that once seemed to require whole neural networks.
An organized tide of brain waves, blood and spinal fluid pulsing through a sleeping brain may flush away neural toxins that cause Alzheimer’s and other diseases.
Machine learning and deep neural networks can capture and analyze the “language” of animal behavior in ways that go beyond what’s humanly possible.
