background image  PSYCHOLOGY 101 NOTES The Brain and Nervous System >the study of the brain and nervous system to better understand the 
functioning and possibilities of the brain
>includes the study of the biological foundations Nervous System  gathers and process information, produces responses to  stimuli and coordinates the working of different cells.  The  Central Nervous  System (CNS)  is composed of brain and spinal cord.  Peripheral Nervous  System (PNS)  are all nervous outside the brain and outside of the spinal  cord.is in charge of sending information (touch, pull) to the spinal cord, then 
finally to the brain. 
PNS
-somatic nervous system (voluntary moment)
-autonomic nervous system
-sympathetic nervous system (energy output)
-parasympathetic nervous system (relaxes and controls energy)
Communication within the Nervous system -Neurons
- Glia Cells (greek for glue). Provide the neurons with nutrients, protect 
neurons. 
-support and strengthen a neuron
-play a huge role in learning and memory.
Structure of Neurons
 A neuron has three parts:
-dendrites: receive messages from other nerve cells
-cell body: nucleus contains genetic info. and helps the cell grow
-axon: transmit the message to wherever the message needs to go. aka 
(myelin sheath: helps the message transmit faster.)
Neurogenesis  refers to the production of new neurons from immature stem  cells. Stem cell research includes three main types of stem cells: embryonic 
stem cells, non-embryonic stem cells and reprograming adult stem cells. 
Neurotransmitters:  1) chemical substance released by a transmitting neuron at the  synapse  2) alters the activity of a receiving neuron 
3) some follow a specific path and some are distributed throughout the
brain  Hormones
