What is the primary function of the neuron?

  1. To transmit electrical signals

  2. To store information

  3. To process information

  4. To generate movement


Correct Option: A
Explanation:

The primary function of the neuron is to transmit electrical signals, known as action potentials, to other neurons, muscles, or glands.

What is the name of the junction between two neurons?

  1. Synapse

  2. Dendrite

  3. Axon

  4. Soma


Correct Option: A
Explanation:

The junction between two neurons is called a synapse, which is a specialized structure that allows for the transmission of electrical or chemical signals from one neuron to another.

What is the role of neurotransmitters in synaptic transmission?

  1. To facilitate the transmission of electrical signals

  2. To inhibit the transmission of electrical signals

  3. To regulate the strength of synaptic connections

  4. All of the above


Correct Option: D
Explanation:

Neurotransmitters play multiple roles in synaptic transmission, including facilitating the transmission of electrical signals, inhibiting the transmission of electrical signals, and regulating the strength of synaptic connections.

What is the name of the process by which neurons communicate with each other?

  1. Synaptic transmission

  2. Action potential propagation

  3. Neurogenesis

  4. Long-term potentiation


Correct Option: A
Explanation:

The process by which neurons communicate with each other is called synaptic transmission, which involves the release of neurotransmitters from one neuron and their binding to receptors on another neuron.

What is the term for the gradual strengthening of synaptic connections over time?

  1. Long-term potentiation

  2. Long-term depression

  3. Synaptic plasticity

  4. Hebbian learning


Correct Option: A
Explanation:

The gradual strengthening of synaptic connections over time is called long-term potentiation, which is a form of synaptic plasticity that is thought to be a cellular mechanism for learning and memory.

What is the name of the process by which the brain reorganizes itself after injury or disease?

  1. Neuroplasticity

  2. Neurogenesis

  3. Synaptic pruning

  4. Axonal sprouting


Correct Option: A
Explanation:

The process by which the brain reorganizes itself after injury or disease is called neuroplasticity, which involves changes in the structure and function of the brain in response to new experiences or challenges.

What is the term for the formation of new neurons in the adult brain?

  1. Neurogenesis

  2. Synaptogenesis

  3. Axonal sprouting

  4. Dendritic arborization


Correct Option: A
Explanation:

The formation of new neurons in the adult brain is called neurogenesis, which occurs in specific regions of the brain and is thought to be important for learning, memory, and mood regulation.

What is the name of the process by which axons grow and form new connections with other neurons?

  1. Axonal sprouting

  2. Synaptogenesis

  3. Dendritic arborization

  4. Long-term potentiation


Correct Option: A
Explanation:

The process by which axons grow and form new connections with other neurons is called axonal sprouting, which is a form of neuroplasticity that occurs in response to injury or disease.

What is the term for the branching of dendrites to form new connections with other neurons?

  1. Dendritic arborization

  2. Synaptogenesis

  3. Axonal sprouting

  4. Long-term potentiation


Correct Option: A
Explanation:

The branching of dendrites to form new connections with other neurons is called dendritic arborization, which is a form of neuroplasticity that occurs in response to new experiences or challenges.

What is the name of the mathematical model that describes the firing rate of a neuron?

  1. Hodgkin-Huxley model

  2. McCulloch-Pitts model

  3. Perceptron model

  4. Hopfield network


Correct Option: A
Explanation:

The Hodgkin-Huxley model is a mathematical model that describes the firing rate of a neuron, taking into account the flow of ions across the neuron's membrane.

What is the term for the mathematical model that describes the behavior of a network of neurons?

  1. Neural network model

  2. Perceptron model

  3. Hopfield network

  4. Kohonen network


Correct Option: A
Explanation:

A neural network model is a mathematical model that describes the behavior of a network of neurons, taking into account the connections between neurons and the firing rates of individual neurons.

What is the name of the mathematical model that describes the learning process in a neural network?

  1. Perceptron learning rule

  2. Backpropagation algorithm
