Most of the signals neurons receive are ; others are the opposite, or inhibitory

The most part of signals recieved by neurons are excitatory meaning they generate a positive change in the membrane which in turn means that the permeability to ions outside the cell changes.

Excitatory.

Explanation:

Most of the signals synapses between neurons are either excitatory or inhibitory that are opposite to others. Inhibitory signals work to cancel the signal and excitatory neurotransmitters to cause the signal propagates.

Neurons communicate with each other with the help of electrical events called action potential. This phenomenon is generated through the flow of positively charged ion, across the neuronal membrane.

Information from one neuron to another neuron across a small gap, called synapse in which electrical signals are converted into chemical signals. On the other side the signal becomes electrical again.

when the displaced particles are perpendicular to the direction the wave travels, is called a transverse wave, whereas in longitudinal wave the displace practices are parallel to the direction of the wave.
