Study Notes
Cognitive Neuroscience
- Aims to explain cognitive processes using brain mechanisms.
- Studies how the brain gives rise to our thoughts, feelings, and behaviors.
Philosophy of Mind
- Explores the relationship between the mind and the brain.
- Dualism: Mind and body are separate entities and interact through the pineal gland.
- Reductionism: Mind and body are one entity, and cognitive concepts can be explained by biological concepts.
Historical Foundations
- Aristotle (380 BC) believed the heart was the center of mental experiences.
- Galen (130 AD) believed ventricles in the brain contained mental experiences circulated by cerebrospinal fluid (CSF).
- Gall (1810) developed phrenology: specific mental functions were located in different parts of the brain, determined by the size of skull bumps.
Functional Specialization
- Different parts of the brain are responsible for specific cognitive functions.
- Modules: Unique information processing categories (e.g., face recognition, object recognition).
- Example: Face processing occurs in the ventral temporal lobe, while risk assessment happens in the prefrontal cortex.
Cognitive Neuropsychology
- Studies brain damage to understand normal brain function.
- Broca (1860) discovered speech production is localized in the left prefrontal cortex, supporting localizationism: a single cognitive function is localized to a single brain area.
The Birth of Cognitive Neuroscience
- Wilder Penfield (1930s) directly stimulated the cortex of awake patients undergoing brain surgery.
- Stimulation induced "mental" sensations like thinking, perceiving, and remembering.
From Modules to Networks
- Current research focuses on brain networks: dynamically changing patterns of activity across multiple brain regions.
- Networks are functionally specialized, switching on or off depending on the required thought or behavior.
Human Connectome Project
- Aims to map all connections in the human brain.
- Understanding brain wiring will improve treatments for neurological and psychiatric disorders.
Neuroanatomy of the Brain
- Neurons: Specialized cells that transmit information using electrical and chemical signals.
- Glial cells: Support neurons structurally and metabolically.
- Cell body: Contains the nucleus and produces proteins for neuron health and communication.
- Dendrites: Branching structures receiving information from other neurons.
- Axon: Long tube sending signals to other neurons.
Neuron Shapes
- Unipolar cells: One process including both axon and dendrite.
- Bipolar cells: Two processes: axon and dendrite.
- Multipolar cells: More than two processes: one axon and multiple dendrites.
Neuron Structure
- All neurons have the same basic structure, but the placement and shape of axons and dendrites vary.
Neurotransmission
- Communication between neurons through electrochemical signals.
- Synapse: Space between neurons where chemical signals are transmitted.
- Neurotransmitters: Chemical messengers released by neurons, influencing the receiving neuron.
