How do proteins in neurons alter excitability, allowing us to think, feel, remember, and forget?

Proteins in neurons play a crucial role in altering excitability by regulating the flow of ions across the cell membrane. Changes in the permeability of the membrane to specific ions, such as sodium ions (Na+) and potassium ions (K+), can result in the generation of electrical impulses, or action potentials.

Which allow neurons to communicate with each other and ultimately enable cognitive processes such as thinking, feeling, remembering and forgetting. There are several types of proteins in neurons that contribute to altering excitability.

For example, ion channels are proteins that form pores in the cell membrane and allow ions to pass through in response to specific signals. There are also ion pumps and exchangers that regulate the concentration of ions inside and outside the cell. This affects membrane potential and excitability.

Additionally, there are proteins that regulate the expression and activity of other proteins, such as receptors and enzymes, which can affect the sensitivity and responsiveness of neurons to various signals. For example, neurotransmitter receptors are proteins that bind to specific chemical signals, such as dopamine or serotonin.

They then activate or inhibit the flow of ions into the cell, ultimately affecting the excitability. Overall, the complex interplay among various proteins in neurons allows for the fine tuning of excitability and facilitates the complex cognitive process that underlie thinking, feeling, remembering, and forgetting.
