Neuronal Plasticity: Synaptic Changes and Brain Functioning

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.
