Pruning and increases in synaptic density are confined to childhood.

The part of the brain at the top of the spinal cord is called the

Which of the following lobes are involved in the ability to do a series of tasks in proper sequence and then to stop doing these tasks at the proper time?

The parasympathetic nervous system acts like an accelerator on a car,mobilizing the body for action and for an output of energy.

Which of the following regions contains the auditory cortex?

The site where a nerve impulse is transmitted from one nerve cell to another is called the

As a critical thinker in psychology,it is important to recognize that

When a nerve cell is stimulated,there is a sudden,momentary inflow of positively charged sodium ions across the cell's membrane,followed by an outflow of positively charged potassium ions.

This procedure allows more precise information about electrical activity in single neurons.

The sympathetic nervous system acts like the _______________ of a car,whereas the parasympathetic nervous system acts more like a(n)_______________.

Which of the following transmit messages away from the cell body to neurons,muscles,or gland cells?

The right side of the brain is superior to the left in problems requiring spatial visual ability and in facial recognition.

Throughout life,axons and dendrites continue to grow,and tiny projections on dendrites,called _______________ increase in size and number.

When an individual's pupils constrict,heart beat slows,and digestion is activated,then the parasympathetic nervous system has become active.

The _______________ is involved in remembering certain simple skills and acquired reflexes.

Research on neurotransmitters has shown that

Spinal reflexes are automatic and cannot be influenced by thoughts and emotions.

A wounded soldier realizes that his best friend has been seriously injured in battle,yet he somehow manages to hoist his buddy over his shoulder,and carry him to safety.How is the soldier able to do this without being disabled by the pain from his own wound?

Which of the following neurotransmitters affects neurons involved in muscle action and cognitive functioning?

Which of the following neurotransmitters affects neurons involved in voluntary movement,learning,memory,emotion,and possibly,response to novelty?
