Transcript of The Human Brain!!!

THE HUMAN BRAIN!!! It processing emotions, and fear–learning.
Associated Functions: Fear-processing, Learning, Fight-or-Flight responce, and Reward-processing
The Amygdala has three functioning parts
The Medial group
The Basolateral group
The Central and Anterior groupA Amygdala! The Brainstem is made up of three parts: Midbrain, Pons, and Medulla.
It maintaines homeostasis by controlling autonomic functions such as breathing, heart rate, and blood pressure.
Associated Functions: maintaining homeostasis by controlling autonomic functions (including blood pressure, breathing, digestion, heart rate, perspiration and temperature), alertness, sleep, balance, and startle response Brain Stem! The cerebellum monitors and regulates motor behavior, particularly automatic movements.
Even though the Cerebellum accounts for 10% of the brain, it contains more neurons than the whole brain combined
Associated Functions: coordination of voluntary movement, motor–learning, balance, reflix-memory, posture, timing, and sequence learning. Cerebellum! The hippocampus is the structure in the brain most closely aligned to memory formation.
It is important as an early storage place for long–term memory, and it is involved in the transition of long–term memory to even more enduring permanent memory.
Associated function: early memory storage, formation of long–term memory, spatial navigation Hippocampus! Corpus Callosum! The Medulla is the bottom/third piece on the brain stem
Associated functions: cardiac, respiratory, vomiting, vasomotor centers,breathing, heart rate and blood pressure Medulla! It receives projections from the retina (via the thalamus) from where different groups of neurons separately encode different visual information such as color, orientation, and motion.
Associated Functions: Vision Occipital Lobe! By: Madeline Pickard Pd. 2 Each hemisphere controls movement in the opposite (contralateral) side of the body as well as passing between information.
The corpus callosum allows information to move between hemispheres and is therefore a very important integrative structure.
Associated with damage:
coma or vegetative state
memory impairments.
Split brain syndrome results in a number of subtle cognitive, movement and perceptual difficulties Temporal Lobe!! Damage to the temporal lobes can result in intriguing neurological deficits called agnosias, which refer to the inability to recognize specific categories (body parts, colors, faces, music, smells).
Associated functions, Recognition, Perception (hearing, vision, smell), Understanding language, Learning and memory Visual Cortex! The Visual Cortex is located in the Occupital Lobe
Associated functions: Vision Angular Gyrus! Broca's Area! Broca's area is a functionally defined structure in the left frontal lobe of about 97% of humans (including a large majority of left–handers)
Associated Functions: language production (both speech and sign), comprehension of complex syntax Cerebral Cortex! Located in the frontal lobe
Includes the cerebrum and cerebellum
Associated Functions : memory, attention, perceptual awareness, thought, language, and consciousness. It is contained in the parietal lobe
Associated Functions: language, mathematics, and cognition Frontal Lobe! The Frontal Love is made up of four different parts.
The frontal lobes are part of the cerebral cortex and are the largest of the brain's structures.
Associated functions: Executive processes (voluntary behavior such as decision making, planning, problem–solving, and thinking), voluntary motor control, cognition, intelligence, attention, language processing and comprehension, and many others. Hypothalamus! the hypothalamus integrates information from many different parts of the brain and is responsive to a variety of stimuli including light (it regulates circadian rhythms), odors (e.g. pheromones), stress, and arousal
Associated functions: hunger, thirst, body temperature, sexual activity, arousal, parenting, perspiration, blood pressure, heart rate , shivering, pupil dilation, circadian rhythms, sleep Motor Cortex! Areas of the motor cortex correspond precisely to specific body parts
Associated functions, coordination and initiation of motor movement Parietal Lobe! It integrates information from the ventral visual pathways (which process what things are) and dorsal visual pathways (which process where things are)
Associated Functions: perception and integration of somatosensory information (e.g. touch, pressure, temperature, and pain), visuospatial processing, spatial attention, spatial mapping, number representation Somatosensory Cortex! The system reacts to diverse stimuli using different receptors: thermoreceptors, nociceptors, mechanoreceptors and chemoreceptors.
Associated Functions: touch, temperature, proprioception (body position), and nociception (pain Thalamus! The thalamus is heavily involved in relaying information between the cortex and brain stem and within different cortical structures.
Associated Functions: relaying motor and sensory information, memory, alertness, consciousness, contributes to perception and cognition Wernicke's Area In about 97% of humans (including a large majority of left–handers) major language functions are contained in the left hemisphere of the brain.
Associated Functions: language comprehension Work Cited!! WWW. g2conline.org
