The strongest brain systems we have are for reproduction, and that brain circuitry can be triggered at any time.
FORBES: The David Petraeus-Paula Broadwell Affair: The Danger Of Male Mentors?
Only later, this argument goes, did the sophisticated brain circuitry for reading gestures get rewired in humans to process speech.
Thus the whole package of beliefs, expectations, likes and dislikes that you hold inside are creating change -- or blocking it -- at the level of brain circuitry.
Researchers at the Society for Neuroscience meeting in New Orleans (Oct 13-17) presented studies showing how stress, no matter its cause, alters brain circuitry in ways that can have long-term effects on mental health.
The "beholder's share" is a deeply personal, socially shaped, active experience rather than the programmed response of brain circuitry that we share with creatures whose entire lives are subordinated to ensuring the replication of the genetic material for which they are vehicles.
One alternative is a proposal that the NIMH has been developing for three years, called the Research Domain Criteria, which will move toward funding research that examines core biological features of illness shared by several disorders, such as problems in brain circuitry, rather than the current practice of focusing on symptoms specific to one disorder, according to Dr. Insel.
Changing a synapse affects the brain's circuitry, and it is the pattern of this circuitry that stores memories though the details are obscure.
Now, it appears more likely that migraines "hijack" the brain's normal pain circuitry, says Dr. Dodick.
After analyzing data from 47 independent brain imaging studies, researchers found that the rule-breaking behavior common to people with antisocial, violent, and psychopathic tendencies may result partly from damage to the neural circuitry in the brain that underlies moral decision-making.
FORBES: Man Allegedly Strikes Toddler on Airplane: What Was He Thinking?
As the answers became less obvious (is a sponge living?), his brain had to bring on more circuitry.
They studied the nerve cells that regulate appetite using a 'genetic fate mapping' technique and found that some cells added neurons to the appetite-regulating circuitry of the mouse brain after birth and into adulthood.
Researchers are learning that precisely targeting barely noticeable pulses to affected areas of the brain can help restore some normal function to the cerebral circuitry.
Many diseases of the brain may be caused by clumps of proteins that clog its circuitry.
The brain is the ultimate computer, with so many cells and synapses and such intricate circuitry that it defies conventional analytical tools.
