Neuronal Plasticity: Synaptic Changes and Brain Functioning

Description

This lecture explores the concept of neuronal plasticity, focusing on the structural and functional changes in neural networks due to experiences. It delves into the variations in synapse number, architecture, and efficiency, as well as the rearrangements within the brain. The lecture also discusses neuronal assemblies, which are groups of neurons with strong synaptic connections that code for specific experiences or objects. It covers the dynamic nature of assemblies, their spatial distribution in the brain, and the principle of 'Neurons that fire together wire together'. Additionally, the lecture touches upon the different modes of brain functioning, including linear, binary, conscious, and unconscious states, as well as the concept of the dynamic unconscious and primary illogical processes. It concludes with insights into the production of unconscious states through various mechanisms like subliminal processing, reconsolidation, repression, and neuronal plasticity.

Human brain

The human brain is the central organ of the human nervous system, and with the spinal cord makes up the central nervous system. The brain consists of the cerebrum, the brainstem and the cerebellum. It controls most of the activities of the body, processing, integrating, and coordinating the information it receives from the sense organs, and making decisions as to the instructions sent to the rest of the body. The brain is contained in, and protected by, the skull bones of the head.

Neural coding

Neural coding (or neural representation) is a neuroscience field concerned with characterising the hypothetical relationship between the stimulus and the individual or ensemble neuronal responses and the relationship among the electrical activity of the neurons in the ensemble. Based on the theory that sensory and other information is represented in the brain by networks of neurons, it is thought that neurons can encode both digital and analog information.

Split-brain

Split-brain or callosal syndrome is a type of disconnection syndrome when the corpus callosum connecting the two hemispheres of the brain is severed to some degree. It is an association of symptoms produced by disruption of, or interference with, the connection between the hemispheres of the brain. The surgical operation to produce this condition (corpus callosotomy) involves transection of the corpus callosum, and is usually a last resort to treat refractory epilepsy.

Synaptic plasticity

In neuroscience, synaptic plasticity is the ability of synapses to strengthen or weaken over time, in response to increases or decreases in their activity. Since memories are postulated to be represented by vastly interconnected neural circuits in the brain, synaptic plasticity is one of the important neurochemical foundations of learning and memory (see Hebbian theory). Plastic change often results from the alteration of the number of neurotransmitter receptors located on a synapse.

Neuroplasticity

Neuroplasticity, also known as neural plasticity, or brain plasticity, is the ability of neural networks in the brain to change through growth and reorganization. It is when the brain is rewired to function in some way that differs from how it previously functioned. These changes range from individual neuron pathways making new connections, to systematic adjustments like cortical remapping. Examples of neuroplasticity include circuit and network changes that result from learning a new ability, information acquisition, environmental influences, practice, and psychological stress.
