The Human Brain


The Human Brain

Despite extensive research on the brain, we still know surprisingly little about it. We are still unsure of the specific functions of various areas and how many processes work.The brain uses 20% of the bodys oxygen and runs on 20 watts of electricity.

A quick virtual tour.Exterior of the Brain

Exterior of the Brain

Frontal Lobe: Contains both the frontal association area as well as the motor strip. Higher reasoning occurs here such as recognizing consequences from current actions and determining our (best) responses in social situations. The Frontal generally reaches maturity in humans during a persons early 20s.Exterior of the Brain

Parietal Lobe: Contains the sensory strip and is important in helping us to understand the sensory information we receive. Also, this area of the brain helps us in understanding representation of numbers, manipulation of objects, and spatial sense.Exterior of the Brain

Occipital Lobe: The visual processing center of the human brain. Damage to the occipital lobe may cause visual hallucinations.Exterior of the Brain

Temporal Lobe: Involved in auditory processing as well as some visual and speech processing. The temporal lobe also plays a vital role in forming long term memory. Examples include: speech comprehension, verbal memory, and recognizing complex visual images such as faces.Exterior of the Brain

Cerebral Cortex: Name given to the outer brain, including the four lobes which covers the inner and lower brain. Higher level thought and processing occurs here.Exterior of the Brain

Motor StripControls movement throughout the body and is found in the frontal lobe.Exterior of the Brain

Sensory StripResponsible for sensation and touch.Exterior of the Brain

Central FissureDivides the two hemispheresLeft HemisphereRight HemisphereMore responsible for logic and problem solvingMore responsible for imagination, feelings, and spatial relationsExterior of the Brain

Cerebellum: Latin for little brain. Helps in coordinating balance, calculates speed and distance of objects, and some motor learning.CerebellumInterior of the Brain

Interior of the BrainHypothalamusPlays a role in regulating hunger and thirst, body temperatures, and circadian cycles.Also involved in emotions such as aggression, sexual behavior, and caring for children.Interior of the Brain

Interior of the BrainPituitary GlandOnly about the size of a pea, yet very important.Called the master glandRegulates hormone secretions in various regions of the bodyDetermines an individuals heightAlso important for regulating metabolism and hormones related to childbirth and breast milk production

Amygdala(around here)Interior of the BrainAmygdalaLocated within the temporal lobePart of the Limbic systemPlays an important role in emotional learning and storage of memories related to emotion such as fear conditioningBrain Cells

Brain CellsBrain cells which are electrically charged and transmit messages from the brain to the body.NeuronBrain Cells

Brain Cells Branches of the neuron which receive electrical charges (information) from one neuron to another.DendritesBrain Cells

SynapseBrain Cells Junction point between dendrites of neurons where electrical charges are passed.SynapseBrain Cells

Brain Cells Long extension of the nerve cell. Transmit messages to dendrites.AxonBrain Cells

Brain Cells The material that forms around the axon to insulate electrical charges. Good myelin covering increases the speed at which messages are transmitted.Myelin Sheath
