i'm doing a project on neurobiology, so only smart ppl plz?

Question

give me any information u have on the following topic, "prefrontal cortex - executive function"

Answer 1

The prefrontal cortex of the brain appears to be a key part of the nervous system controlling working memory. Advanced imaging techniques were first used in 1997 to show the moment-by-moment brain activity involved in seeing a face or a series of letters, holding it briefly in working memory, and then recalling it. Two research teams supported by the National Institute of Mental Health (NIMH) reported on the studies using functional magnetic resonance imaging (fMRI) Working memory disorders, such as schizophrenia, illustrate the importance of the "executive functions" of the prefrontal cortex which include decision making, attention, and planning. Researchers believe that the high concentrations of nerve fibers containing the neurotransmitter dopamine are central to working memory and executive functions. Neurotransmitters are chemicals which transmit messages from neuron to neuron via synapses. They act by binding to molecules called receptors. Monkeys have been used extensively to study the effects of various chemicals on the brain. The figure at the right shows the brain of a monkey and the prefrontal cortex. Executive functions associated with the prefrontal cortex and working memory include:
- initiation and overall control of deliberate actions
- initiation and overall control of goal directed behavior
- attention
- planning
- decision making

Answer 2

The executive functions include:

* initiation of and overall control of the execution of deliberate actions
* initiation of and overall control of goal directed behavior
* attention
* planning
* decision making
