Study Notes
Biological Psychology Fundamentals
- Biological psychology examines how biological systems influence behavior.
- Behavior encompasses any action or response from an organism due to stimuli.
Theories of Mind and Body
- Monism proposes a single underlying reality, viewing body and mind as one.
- Dualism believes in the existence of both body and mind as separate entities.
Reflexes and Neural Pathways
- Reflexes are involuntary responses triggered directly by stimuli through a sensory receptor to muscle connection.
- The Bell-Magendie Law describes how spinal nerves carry sensory information via the dorsal root and motor commands via the ventral root.
Nervous System Functionality
- The Doctrine of Specific Nerve Energies states that sensory messages are determined by the specific nerves transmitting them.
- Pressure phosphenes occur when pressure is applied to the optic nerve, causing visual sensations.
Historical Perspectives on Brain Function
- Phrenology, developed by Gall, suggested mental functions are localized in the brain; head bumps indicated moral and intellectual characteristics.
- The cerebrum is the uppermost section of the brain, integral to higher brain functions.
Language and Brain Areas
- Broca's Area, located in the frontal lobe, is crucial for speech production.
- Wernicke's Area, found in the temporal lobe, is essential for understanding language and generating coherent speech.
Memory and Learning Processes
- Engrams represent physical locations of specific memories in the brain.
- Mass Action indicates that damage to larger brain areas leads to more significant impairments in learning.
Concepts of Brain Plasticity
- Equipotentiality posits that any part of a functional area could serve its function, highlighting brain adaptability.
- Ablation techniques involve removing brain parts or destroying neurons to study their functions.
Research Tools and Techniques
- Stereotaxic apparatus allows precise lesions in targeted brain regions for experimental studies.
- Imaging techniques like CAT and MRI generate static brain images using x-rays and magnetic fields respectively.
- EEG records electrical activity across the cerebral cortex, while PET measures metabolic activity to assess neural function.
Electrode Types and Recording Techniques
- Macroelectrodes capture signals from numerous neurons collectively.
- Microelectrodes focus on the activity of individual or small groups of neurons.
Advanced Imaging and Analysis
- fMRI assesses cerebral blood flow related to neural activity, providing insights into brain function during tasks.
- Autoradiography uses radioactive chemicals to trace locations of specific substances in neural tissues.
- Microdialysis is a technique for measuring specific chemicals in the brain by monitoring freely diffusing substances.
