Hindbrain
Medulla- The first part of the brain, taking place at the top of the spinal chord, it takes care of the most important parts of living, such as heartbeat, breathing, and swallowing.
Pons- Meaning bridge, it is located just above the Medulla, it controls parts of sleep, dreaming, left-right body coordination, and arousal.
Reticular Formation- Involved heavily in the brains ability to focus on specific data and to ignore others. Also controls our ability to be awake and attentive.
Cerebellum- Located in the lower part of the brain just above the spinal chord, it controls coordination of involuntary, rapid, and fire motor movement.
Limbic structures
Thalamus- In the center of the brain, it takes information from the lower parts of the brain and sorts out where to send it from there. It also plays a big part in all of the senses except for smell. Weird...
Hypothalamus- Just below the thalamus, and right above the pituitary gland, this deals with motivational behavior such as sleep, hunger, thirst, and sex.
Hippocampus- Located in both temporal lobes, it is responsible for the formation of long-term memories and where objects are.
Amygdala- Next to the hippocampus, it deals with our responses to fear.
Cortex- The outside covering of the brain that is made of tightly packed neurons.
Hemispheres- The two sections of the brain, the left and the right.
Occipital- The section of the brain located at the rear and bottom of the brain. It deals primarily with sight.
Parietal- Found at the top and back of each hemisphere they are the centers for touch, taste, and temperature
Temporal- Responsible for hearing and the recognizing of speech.
Frontal- Responsible for the higher mental processes, decision making, and speaking fluently. These lobes also contain the motor contex, controlling our movements.
Association Areas
Broca's Area- this area, generally located in the left frontal lobe deals with speaking fluently. People with damage to this part of the brain have what is called Broca's aphasia, and they typically can't use or understand language.
Wernicke's Area- In the left temporal lobe, this area deals with the understanding of speech. Someone with damage to this part of their brain would have Wernicke's aphasia, and they wouldn't be able to understand others or the words that would come out wouldn't make any sense.
