Study Notes
The Central Nervous System
- The brain floats in cerebrospinal fluid (CSF) secreted by the choroid plexus in the ventricles.
- Pia mater adheres to the surface of the brain and spinal cord.
- The meninges and extracellular fluid cushion the delicate brain tissue.
Brain Function
- Brain follows a basic reflex pathway: receives sensory input, integrates and processes the information, and creates a response if appropriate.
- Brain generates information and output signals in the absence of external output.
- An approach to modelling brain function involves three systems that influence output by the motor systems of the body: sensory system, cognitive systems, and behavioral state system.
Cerebral Cortex
- The cerebral cortex serves as an integrating center for sensory information and decision-making region for many types of motor output.
- The cerebral cortex can be divided into three specializations: sensory, motor, and association areas.
Learning and Memory
- Learning has two broad types: associative learning and nonassociative learning.
- Memory is the ability to retain and recall information.
- Memories are stored throughout the cerebral cortex in pathways known as memory traces.
- Several types of memories: short-term, long-term, reflexive, and declarative.
- Processing of different memory takes place through different pathways.
Hippocampus
- In humans, the hippocampus is important in both learning and memory.
- Patients with part of destroyed hippocampus can have epilepsy and trouble with remembering new information.
- Anterograde amnesia is the inability to remember new information.
- Memory loss in the elderly can be caused by dementia and Alzheimer's disease.
Language
- Language skills require the input of sensory information, processing in various centers in the cerebral cortex, and the coordination of motor output for vocalization and writing.
- Most people, the center of language ability is in the left hemisphere.
- The ability to communicate through speech has two processes: the combination of different sounds to form words and the combination of words into grammatically correct and meaningful sentences.
- Integration of spoken language involves two regions in the cerebral cortex: Wernicke's area and Broca's area.
Personality
- Personality is a combination of attributes that are influenced by experience and inheritance.
- What we learn or experience and what we store in memory create a unique pattern of neuronal connections in our brains.
- Sometimes, these circuits malfunction, creating depression, schizophrenia, and other disorders.
- Schizophrenia has both genetic and environmental basis.
