Novel 'top-down' mechanism repatterns developing brain regions

Dennis O'Leary of the Salk Institute was the first scientist to show that the basic functional architecture of the cortex, the largest part of the human brain, was genetically determined during development. But as it so often ...

Neuroscience

Why are sounds not perceived under anesthesia?

The purpose of anesthesia is to put the brain into an unconscious state in which stimuli such as sounds are not perceived. In this state, the neurons in the auditory cortex are still stimulated by sounds, but the latter are ...

Study details brain pathways linking visual function, running

A new study by researchers at the University of Oregon published today in the journal Neuron describes a brainstem circuit in mice that may help explain how active movement impacts the way the brain processes sensory information.

Neuroscience

Persistent sensory experience is good for aging brain

Despite a long-held scientific belief that much of the wiring of the brain is fixed by the time of adolescence, a new study shows that changes in sensory experience can cause massive rewiring of the brain, even as one ages. ...

Neuroscience

The auditory cortex adapts agilely with concentration

The birth of sensory perception on the human cerebral cortex is yet to be fully explained. The different areas on the cortex function in cooperation, and no perception is the outcome of only one area working alone. In his ...

Somatostatin neurons cooperate in the cerebral cortex

The brain's cerebral cortex is made up of distinct regions involved in myriad processes, from sensory perception to cognitive functions like memory, attention, and decision-making. University of Pittsburgh neuroscience researchers ...
