A subfield of neuroscience known as "cellular neuroscience" focuses on the cellular level investigation of neurons. The morphological and physiological characteristics of a single neuron are included in this. Numerous methods have been used to examine cellular activity, including intracellular recording, patch-clamp and voltage-clamp techniques, molecular biology, confocal imaging, pharmacology, and Ca2+ imaging. Cellular neuroscience studies the diverse neuronal types, their functions, how they interact with one another, and how they influence one another.

Cells with the ability to receive transmit, and spread electrical signals are known as neurons. More than 80 billion neurons are found in the human brain alone. Neurons have a wide range of morphologies and functions. The prototypical motor neuron, which has dendrites and myelinated axons that carry action potentials, does not apply to all neurons. Action potential-conducting myelinated axons are not present in all neurons, including photoreceptor cells. There are also unipolar neurons in invertebrates, but they lack even defining features like dendrites. Additionally, it is useless to distinguish between neurons and other cells like cardiac and muscular cells based on their functions.

Excitability is a major feature of many neurons. Action potentials and graded potentials are the two different types of electrical impulses or voltage changes that neurons produce. Gradient potentials happen when the membrane potential depolarizes and hyperpolarizes in a graduated manner in relation to the strength of the stimulus supplied to the neuron. On the other hand, an action potential is an all-or-nothing electrical impulse. Action potentials have the benefit of reaching large distances in axons with minimal to no degradation, but being slower than graded potentials.

Through synapses, neurons can communicate with one another. Specialized connections in close proximity to one another between two cells are known as synapses. The presynaptic neuron in a synapse provides the signal, and the postsynaptic neuron or cell receives the signal from the target cell. Chemical or electrical synapse types exist. Gap junctions, which allow ions and other organic compounds to instantly move from one cell to another, are formed at electrical synapses. Neurotransmitters released pre synaptically at chemical synapses diffuse across a synaptic cleft to connect with postsynaptic receptors. In order to interact with their postsynaptic target cells, neurons release neurotransmitters, which are chemical messengers produced within the neurons themselves.

Voltage-gated calcium channels located in the membranes of these boutons are activated when the voltage in the terminal bouton changes. These permit Ca2+ ions to pass through and interact with synaptic vesicles at the terminal boutons. When the vesicles are coupled with Ca2+, they dock, fuse, and release neurotransmitters into the synaptic cleft in a process known as exocytosis. Following this, the neurotransmitters bind to postsynaptic receptors ensconced on the postsynaptic membrane of an additional neuron by diffusing across the synaptic cleft. Ionotropic and metabotropic receptors belong to different families of receptors.
