Neurotransmitters are chemicals that are involved in communication between the nervous system and endocrine glands. It is basically a chemical message.

The embryonic origin of all neural tissue?

Neural tissue originates from the ectoderm layer of the developing embryo. This layer gives rise to the neural tube, which later differentiates into the central nervous system (brain and spinal cord) and the peripheral nervous system. Neuromesodermal progenitors are involved in the development of both neural and mesodermal tissues during embryonic development.


What is the difference between tonic and phasic responses in the context of neural activity?

Tonic responses are continuous and sustained neural activity, while phasic responses are brief and transient bursts of neural activity.


What is neural coding?

Neural coding is the process by which the nervous system represents and processes information. It involves the conversion of sensory stimuli and other sources of input into patterns of neural activity, which are then interpreted by the brain to generate perception, thoughts, and behaviors. Different types of neural coding mechanisms exist, such as rate coding (based on firing rate of neurons) and temporal coding (based on the timing of neural spikes).


What is epochs in neural network?

In a neural network, an epoch refers to one complete pass of the entire training dataset through the neural network. During one epoch, the model updates its weights based on the error calculated from the predictions compared to the actual target values. Multiple epochs are typically required to train a neural network effectively.


Where do neurons originate in the human body?

Neurons originate from neural stem cells in the developing embryo, primarily in the neural tube.
