Central Nervous System consists of:
The brain and spinal cord
The brain and spinal cord make up the:
Central Nervous System
Cerebral Cortex
-more developed in humans than in any other animal
-what we see when we imagine a brain
-involved in a variety of higher cognitive, emotional, sensory, and motor functions
Cerebrum
1. the anterior and largest part of the brain, consisting of two halves or hemispheres and serving to control voluntary movements and coordinate mental actions.
2. the forebrain and the midbrain.
Frontal Lobe/Motor Cortex
1. motor behavior
2. expressive language
3. higher level cognitive processes
4. orientation to person, place, time, and situation
Parietal Lobe/Somatosensory Cortex
processing of:
-touch
-pressure
-temperature
-pain
Occipital Lobe/Visual Cortex
interpretation of visual information
Temporal Lobe/Auditory Cortex
-receptive language
-memory
-emotion
Brainstem
-part of spinal cord
-life-sustaining functions
-damage to this often fatal
Medulla Oblangata
-heartbeat
-breathing
-blood pressure
-digestion
-part of the brainstem
Reticular Activating System/ Reticular Formation
-arousal and attention
-sleep and wakefulness
-control of reflexes

part of brainstem
Pons
regulates states of arousal, including sleep and dreaming.

part of brainstem
Cerebellum
-balance
-smooth movement
-posture
-part of brainstem
Thalamus
"central switching station" – relays incoming sensory information (except olfactory) to the brain

part of brainstem
Hypothalamus
controls autonomic nervous system, and therefore maintains the body’s homeostasis(controls body temperature, metabolism, and appetite. Translates extreme emotions into physical responses.

part of brainstem
Limbic System
emotional expression, particularly the emotional component of behavior, memory, and motivation

part of brainstem
Amygdala
attaches emotional significance to info, mediates defensive/aggressive behavior

part of brainstem
Hippocampus
memory, transfer of info from short-term to long-term memory
Peripheral Nervous System
divided into two sub-systems

not a part of brain or brainstem
Somatic Nervous System
regulates actions of skeletal muscles

mediating voluntary activity
Autonomic Nervous System
regulates primarily involuntary activity such as: heart rate
breathing
blood pressure
digestion

these activities can be altered either through specific events or through changing our perceptions about a specific experience.

further broken down into two systems:

Sympathetic and Parasympathetic Nervous Systems.
Sympathetic Nervous System
"Fight or Flight"
Parasympathetic Nervous System
slow acting

controls the calm-down after fight or flight
