  • 3rd side (hint)
Frontal lobe
Integrated brain functions: thinking, conceptualizing, planning, conscious appreciation of emotion, motor
behavior, expressive language, orientation
http://tinyurl.com/jvmtd2s
Parietal lobe
Mainly deals with movement, orientation, calculation, and certain types of recognition
http://tinyurl.com/kw7ety9
Temporal lobe
Deals mainly with sound, speech comprehension (usually only on the left), some aspects of memory
http://tinyurl.com/m3hxjsn
Occipital lobe
Mostly handles visual processing areas
http://tinyurl.com/kuubelz
Medulla oblongata
(continuation of the spinal cord into the brain) – controls breathing, heart rate, blood pressure, digestion, skeletal muscle tone
http://tinyurl.com/lvxle5k
The reptilian brain, or brainstem
contains structures necessary to keep us alive: (Medulla oblongata and Pons_
http://tinyurl.com/kzfa7vb
Pons
connects the medulla, and extends into, the midbrain reticular activating formation – governs alertness, waking, sleeping, muscle tone, some reflexes
http://tinyurl.com/mt7v9om
Midbrain
continuation of the brainstem; midbrain “subthalamus” + basal ganglia + cerebellum make up the extrapyramidal motor system. All information passing from spinal cord to the higher brain goes through this area or structure
http://tinyurl.com/qefe9x2
Cerebellum
“little brain” – critical for smooth, coordinated movement, balance; also connected to auditory and visual systems.
http://tinyurl.com/oz4ftnv
Midbrain, pons, & medulla oblongata
Connect cerebral hemispheres and the thalamus-hypothalamus to spinal cord
Contain reticular activating system, most of the nuclei of the cranial nerves, and the major tracts from the spinal cord
Coordinate swallowing, vomiting, and reflex activity of the heart and respiratory systems
Limbic System
Also part of the Mammalian Brain,

Helps us attach emotional meaning to sensory stimulation. Different definitions of inclusion – what constitutes this system - exist.
by most definitions it includes the amygdala, the septum, the hippocampus, and portions of the thalamus, and basal ganglia.
Limbic system
Archaic term for hypothalamus, amygdala, septum, olfactory nuclei, basal ganglia, and hippocampus

Critical in motivation
Helps integrate motor, cognitive and motivational systems
http://tinyurl.com/ogjsesf
Hippocampus
crucial to formation of recent memories
amygdala
integrates and directs emotional behavior, attaches emotional significance to what the senses signal, and mediates defensive aggressive behavior.
Damage produces fear and aggression
septum
inhibits emotionality. Damage produces uninhibited rage and aggression (septal rage syndrome). Also part of pleasure center.
moves signals from short term memory to long term memory.
moves signals from short term memory to long term memory.
basal ganglia
lie at the central regions of the cerebral hemispheres and are systems of cellular nuclei which effect voluntary movement. They are the primary part of the extrapyramidal motor system.
Amygdala
has a central role in anxiety states
Transmits signals to the cortices, limbic areas and brain stem structures

Consider:
Panic disorder
Generalized anxiety
Social phobia
Agoraphobia
Post-traumatic stress disorder
Obsessive compulsive
New Brain (Neocortex)
There are two halves to the upper portion of the brain – hemispheres.
The outermost portion of each cerebral hemisphere is called the cortex. This is what allows us to think, be self aware.
The cortex is divided into 4 lobes by deep grooves in the surface (sulci) – frontal, parietal, occipital, temporal.
The frontal lobes are involved in motor behavior, expressive language, concentration, orientation (time, place, person), thinking and reasoning. These lobes contain the pyramidal system that is involved with fine, intricate movements.
Broca’s area,
The left frontal lobe contains this portion of the brain which helps in speech production (expressive). If damaged – expressive aphasia.
The temporal lobes
are related to receptive language, memory, and emotion. They contain Wernicke’s area, which helps in comprehending language. If damaged – receptive aphasia.
left frontal lobe
contains Broca's area, which helps in speech production (expressive). If damaged – expressive aphasia.
Wernicke’s area
The temporal lobes are related to receptive language, memory, and emotion. They contain this portion or area of the area, which helps in comprehending language. If damaged – receptive aphasia
Parietal lobes
contain the somatosensory cortex, which receives and identifies sensory information from skin receptors, and processes visual and auditory information. Damage here can cause Gertsmann syndrome – inability to write, mathematically calculate, or distinguish between right and left
Gertsmann syndrome
inability to write, mathematically calculate, or distinguish between right and left.
Spinal Cord
the Traffic Controller or mediator. It transmits impulses to and from the brain and the body.

part of the Central Nervous System because it merges into the brainstem.

connects to the Peripheral Nervous System (everything outside the CNS).
Peripheral Nervous System
everything in the nervous system outside the CNS
Central Nervous System (CNS):
Brain and Spinal Cord
Peripheral Nervous System
Somatic (sense receptors, skeletal
muscles)
Autonomic (visceral) - involuntary
Sympathetic nervous system
active in arousal – fight or flight
Parasympathetic nervous system
active in conservation of energy – return to homeostasis
