Building Better Brains: Understanding the Complexities of the Nervous System

⚡Neurons are the building blocks of the nervous system and consist of a cell body, dendrites, and an axon.

🔌Neurons transmit information through electrical signals that travel along the axon and chemical signals released at synapses.

🔁Synapses undergo continuous modification and plasticity, strengthening or weakening connections between neurons.

🌡️The pain system involves sensory neurons that detect noxious stimuli and relay them to the brain for processing.

👂Auditory processing involves the reception and interpretation of sound waves by specialized neurons in the inner ear and brain.

What are the main components of a neuron?

—A neuron consists of a cell body, dendrites, and an axon.

How do neurons transmit information?

—Neurons transmit information through electrical signals along the axon and chemical signals at synapses.

What is synaptic plasticity?

—Synaptic plasticity refers to the ability of synapses to change their strength, which is crucial for learning and memory formation.

How does the pain system work?

—The pain system involves sensory neurons that detect noxious stimuli and transmit them to the brain for processing.

What is auditory processing?

—Auditory processing is the perception and interpretation of sound waves by specialized neurons in the inner ear and brain.
