Biology of Psychology Neurotransmitters Glial cells Cells that provide support and nutrition to the nervous system Keep neurons in their proper place Destroy and eliminate dead neurons and then often replace those neurons Help to make sure that signals do not get crossed Kind of neurons Sensory Neurons - Carry incoming information from the sense receptors to the CNS Motor Neurons - Carry outgoing information from the CNS to muscles and glands Interneurons - Connect the 2 neurons Nervous System Central Nervous System Brain and spinal cord primarily Interconnected neurons form networks in the brain. These networks are complex and modify with growth and experience Peripheral Nervous System Sensory motor neurons that connect to the CNS to the rest of the body Autonomic - Controls self-regulated action of internal organs and glands. Heart rate, digestion, breathing. Happens automatically. Sympathetic- Division of ANS that arouses the body, mobilizing it's energy in stressful situation (fight-or-flight) Parasympathetic-Division of the ANS that calms the body, conserving its energy (rest & digest) Somatic - Controls voluntary movements to skeletal muscles Brain Brainstem Oldest part of the brain, beginning where the spinal cord swells, enters the skull. It is responsible for automatic survival functions Medulla Oblongata The point where the spinal cord enters the skull and joins with the brain Entirely controls the heart rate Largely controls breathing, swallowing, and digestion (Also, sneezing, coughing, and vomiting.) Neurons cross over to the other side of the brain here as well Even the slightest damage in a critical region of the medulla can cause death Pons Relay Station containing neurons that pass signals from one part of the brain to another Fine-tunes motor messages Processes some sensory information, especially visual info Helps control respiration Influence facial expressions Thalamus The brain's sensory switchboard, Directs messages to the sensory area in the cortex and transmits replies to the cerebellum and medulla. Located just beneath the cerebral cortex at about eye level in the center of the brain Reticular Activating System Essential to the regulation of sleep, wakefulness, arousal, and even attention Vital function as heart rate and breathing Also linked to sleep cycle Cerebellum Controls body coordination, balance, and muscles tone Located back of the head, called "little brain" Two wrinkled hemispheres covered by an outer cortex The primary function is to coordinate and regulate motor movements Damage results in awkward, jerky, uncoordinated movements and may affect speech Lymbic System -a donut shaped system of neural structures at the border of the brainstem and cerebrum, associated with emotions such as fear, aggression, and drives for food and sex. ' Amygdala Two lima bean sized neural cluster linked to the emotion of fear and anger (aggression) Hypothalamus Lies below (hypo) the thalamus. Directs several maintenance activities like eating, drinking, body temp, and control of emotions. Helps govern the endocrine system via the pituitary glands Hippocampus Memory Formation Problems result in deficits in memory for facts but not in memory for courses of action May also be involved in regulation of some reproductive characteristics like female sexual behavior, the onset of puberty, and the release of pituitary hormones Structure of the Cortex - Each brain hemisphere is divided in to 4 lobes that are separated by prominent fissures. Frontal Lobes Behind the forehead Control of voluntary muscles, intelligence, personality Phineas Gage Emotionally shallow, distractive, unaware of social mores Prefrontal cortex- higher cognitive functions such as planning , reasoning, self-control, monitors and organizes thinking Parietal Lobe Top and rear of the head Registers spatial location, attention, and motor control
