Consequences of Aging
Delayed Reflexes
-All result of degredation of CNS
Molecular Neuroscience
Study of function at molecular level in regards to messengers (communicate), conductors (growth), archivists (memory)
Cellular Neuroscience
How molecules work together within a cell
-Different neuron types and functions
-Neuron computations
Systems Neuroscience
How neural circuits analyze sensory information, form perceptions, execute movements within a system (motor system)
Behavioral Neuroscience
How neural systems work together to produce behavior, mood, dreams
-Broken Mind
-Loss of touch with reality
-Advanced stages are seen as symptoms of Parkinson's
-Motor Problems
-Flat affect, disinterested facial expressions
Cognitive Neuroscience
Neural mechanisms underlying consciousness, mental imagery, language and action
Galvani's Discovery
Nervous tissue produces electrical activity when excited
Gall's Beliefs
-Behavior stems from the brain
-Particular regions of cortex controlled specific functions
-Behavior was due to activity in brain
-Center for each function grew with use and caused overlying skull to bulge
-Globalization of function
-Characteristics inside skull told where in the brain you had more growth
Gall's Mistake
Instead of examining neural tissue, he correlated that ridges push on the skull to increase size of skull instead of brain tissue actually growing
Ramon y Cajal's finding
Neurons form a network of discrete cells.
Neurons are the elementary signaling units of the nervous system
Two vies of Brain and Behavior
1. Aggregate-Field View
2. Cellular Connectionist View
Aggregate-Field View
-Cerebral hemispheres participated in all mental function
-All was connected
Cellular Connectionist View
-Neurons are the signaling units of the brain arranged in functional groups connected to each other in a precise fashion
-Multiple systems in the brain are organized in a hierarchy and are parallel. Damage in one part allows other parts to take over.
-Therapists depend on ability to re-train other parts of brain
Broca's Finding
-Speech is located in frontal cortex of brain.
Broca's patients
-Loss of the ability to speak was damage in area of frontal cortex
-Oppressive Aphasia - Could respond to unrelated questions
Wernicke's Finding
-Ability to understand speech is located in temporal lobe
Wernicke's Patients
-Had speech but couldn't understand
-Expressive Aphasia - Absence of Expressive Speech
7 Parts of the CNS
-Spinal Cord
-Medulla Oblongata
-Cerebral Hemispheres
Spinal Cord Function
Allows sensory nerves to receive stimulus from periphery and send mesages to brain, in return a response to muscle is given.
Medulla Oblongata Function
Breath, Chew, Basic Operations
(Injury can result in death)
Pons Function
Basic Behaviors
Conduit of information from higher cortical areas to cerebellum
Cerebellum Function
Balance and coordination
Midbrain Function
Control of eye movements, coordination of visual and auditory
Diencephalon Contains
Consists of thalamus and hypothalamus
Thalamus Function
Communication between the cerebral cortex and a number of structures in the lower CNS
Hypothalamus Function
Controls the Autonomic Nervous System
Cerebral Hemisphere Function
Seat of all high level human behaviors
Frontal Lobe Function
Planning future action
Parietal Lobe Function
Somatic sensation, spatial representation
Occipital Lobe Function
Temporal Lobe Function
Hearing, Learning, Memory
Right Side of Brain Involved In?
Music, Art, Representation
Left Side of Brain Involved In?
Arithmetic, Language, Calculations
