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
|

Occipital lobe
|
Mostly handles visual processing areas

Medulla oblongata
|
(continuation of the spinal cord into the brain) – controls breathing, heart rate, blood pressure, digestion, skeletal muscle tone
|

|
|
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
|

|
|
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

|
|
Cerebellum
|
“little brain” – critical for smooth, coordinated movement, balance; also connected to auditory and visual systems.
|

|
|
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 |

|
|
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.

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
