Frontal Lobe

• http://www.epilepsyfoundation.org/answerplace/Medical/seizures/syndromes/images/frontallobe.gif• http://faculty.washington.edu/chudler/lobe.html• http://www.neuroskills.com/tbi/bfrontal.shtml• In control movie

• “Concerned with reasoning, planning, parts of speech and movement (motor cortex), emotions, and problem-solving.”

• “The frontal lobes are considered our emotional control center and home to our personality.”

• Located in the front part of your head

•The thinking part of the brain

Occipital Lobe

• Region in the back of the brain which processes visual information.

• Occipital creates visual cortex

Parietal Lobe

• “Cognition - The mental process of knowing, including aspects such as awareness, perception, reasoning, and

knowledge. • Information Processing • Pain and Touch Sensation • Spatial Orientation - Defines our

natural ability to maintain our body orientation and/or posture

• in relation to the surrounding environment

• Speech • Visual Perception “

Temporal Lobe

• “The temporal lobes are parts of the cerebrum that are involved in speech, memory, and hearing.”

Dendrites

• “Dendrites – branching “fingers” receive signals from axons and send them to the body.”

• http://www.brainexplorer.org/brain-images/dendrite.jpg• Braindemonium posters

Synapse

• Synapse – the gap between neurons where signals pass

• The tiny space between neurons – where signals “jump” to different neurons

nerve_cell_body.html

• the cell body is the central part of the neuron

•The cell body also contains many other unique structures responsible for making energy and getting rid of cellular wastes.

Axon

• Axon – “the long “tail” sends signals over synapse to the dendrites of other neurons”

Thalamus

• “Processes sensory information

• (touch, pain, pressure, heat, cold)”

Hypothalamus

• “Hypothalamus – controls body temperature, sleep, appetite, thirst”

• Pea sized temperature controller, also controls your appetite and emotions

The Pituitary Gland

• The pituitary is a small, pea-sized gland located at the base of the brain

• http://www.pituitary.org/faq/• Pituitary gland – produces

hormones and also controls growth

Amygdala

• “Amygdala – responds to potential threats

• (the brain’s 911 system)”• Your amygdala responds

to things that scare you

Cerebellum

• The cerebellum controls movement and balance

• Braindemonium posters• The cerebellum is the

least developed out of all of the parts of the brain.

Cerebrum

• The cerebrum -- which is just Latin for "brain" -- is the newest (evolutionarily) and largest part of the brain as a whole.  It is here that things like perception, imagination, thought, judgment, and decision occur.

Medulla• The medulla controls breathing

and heartbeats• “Medulla Oblongata - The

medulla oblongata functions primarily as a relay station for the crossing of motor tracts between the spinal cord and the brain. It also contains the respiratory, and cardiac centers, as well as many mechanisms for controlling reflex activities such as coughing, gagging, swallowing and vomiting. “

Movie Notes

• The nervous system is like a telephone system• There is a tiny space between neurons called a

synapse• Sensory neurons go to the spinal chord• The bulge at the top of the spinal chord is the

brain stem• The cerebrum is the largest part of the brain• The brain and the spinal chord - central part of

the nervous system
