Transcript of The Brain
The Brain Stem
*The pons regulates sleep and dreaming cycles.
*Also serves as a communications and coordination center between the two hemispheres of the brain.
*The medulla is the lowest part of the brain and it is about an inch long regulates basic body functions like breathing, digestion, heart and blood vessel function, swallowing and sneezing.
*Motor and sensory neurons from the midbrain and forebrain travel through the medulla.
(also known as Medulla Oblongata)
*Is located behind the spinal cord and looks like a little brain
- fine movement coordination
-balance and equilibrium
The Limbic System
*The reticular formation is a group of nerve fibers located inside the brainstem.
* It keeps the brain awake and alert.
* It also monitors incoming sensory messages.
*Located on top of the brain stem and under the cortex
*Involved in establishing new information and long-term memories.
~Connects your present to your past
~Consolidation of New Memories
~Spatial Orientation (Sense of direction, Visualization, and Reading maps)
*Involved in memory and emotion paticularly in fear and agression
~Autonomic Responses Associated with Fear
*Serves as brains blood-testing laboratory, constantly monitors blood to determine conditon of the body.
~Autonomic Function Control
~Endocrine Function Control
~Motor Function Control
~Food and Water Intake Regulation
~Sleep-Wake Cycle Regulation
*The top most layer of the brain: bulbous cap over limbus system (thinking cap).
At the bottom back of the brain, under the parietal lobes adnd beside the temporal lobes.
It interprets visual input from the retina Involved in:
It is located in front of the occipital, and below the frontal and parietal lobes.
