In chapter 3 of the book Connectome: How The Brain’s Wiring Makes Us Who We Are, the author talked about a type of cell in our brain, Neuron. Neurons are round in shapes, they embrace one another, and this is to make it easier for the signals to transfer to one another. Neurons have a long branches attached to their cell body, it is called Neurite. Neurites are crowned with one another closely but they do not touch. This is to make it easier for the Synapse, which is the junction between Neurons, to work better. Synapses are used when two Neurons need to “contact” with each other, however, “communications” at the Synapses can only be between two neurons, and anything more than that would not work.
If we talk more about how can the Neurons make the brain works, we would have to mention something else, Neurotransmitter. Neurotransmitters are a type of chemical in our body that transfer signals from one neuron to another Neuron, their shapes are determined by the arrangements of their atoms, and there are different types of Neurotransmitters, each type has its own particular shape.

Get AccessThe nervous system is made up of basic units called neurons. The main role of the neurons is to receive, integrate and transmit information throughout the body. There are some neuroglial cells found in nervous system aswell which provide support to the neurons by giving protection and nourishment Neurons have nerve processes that looks like finger like projections extended from the nerve cell body. They also contain axons and dendrites which enable them to transmit signals throughout the body. Normally, axon carry signals away from the cell body and dendrites carry signals toward the cell body according to Regina Bailey (2013). Neurons have three different shapes: bipolar, unipolar and multipolar where bipolar has two neuronal processes coming out of the cell body, unipolar has only one neuronal process coming out of the cell body and multipolar has many neuronal processes coming out of the cell body.
Neurons, nerve cells, have three basic parts: the cell body, dendrites, and axon. Neurons transmit signals to other nerve cells and throughout the body. They are simple components in the nervous system. The cell body includes the nucleus, which is the control center of the neuron. The dendrite branches off the cell body and receives information. The axon is attached to the cell body and sends information away from the cell body to other cells. When the axon goes through myelination, the axon part of the neuron becomes covered and insulated with fat cells, myelin sheath. This increases the speed and efficiency of information processing in the nervous system. Synapse are gaps between neurons, this is where connections between the axons and dendrites.
Neurons are information- processing units in the central nervous system that receive and transmit information. It is made up of an axon, dendrites and a cell body. The nucleus and cytoplasm are contained in the cell body. The axon starts from the cell body, dividing into smaller branches and then ends at the nerve terminals. The dendrites also branch from the cell body, receiving information from the other neurons. Axons from other neurons forms
Everything we do is a product of neural communication, whether that be reacting to senses or feeling emotions, it is all due to us having neural communication through millions of neurons passing small electrical signals throughout the body through such pathways as the central nervous system and the peripheral nervous system and passing information to and from the brain. These ‘’neurons’’ are made up of Dendrites which are connected to a cell body, or also known as the soma, these are tree-like feathery filament ‘’message receivers’’ that collect these messages from other neurons it is connected to, neurons are connected through a dendrite to axon terminal connections and pass these ‘’messages’’ through the body as action potentials.
A synapse is a link where neurons communicate with other cells across narrow gaps using neurotransmitters or pulses (I learned this in my biology course last semester).
Neurotransmitters are chemicals made by neurons and used by them to transmit signals to the other neurons or non-neuronal cells (e.g., skeletal muscle; myocardium, pineal glandular cells) that they innervate. The neurotransmitters produce their effects by being released into synapses when their neuron of origin fires (i.e., becomes depolarized) and then attaching to receptors in the membrane of the post-synaptic cells. This causes changes in the fluxes of particular ions across that membrane, making cells more likely to become depolarized, if the neurotransmitter happens to be excitatory, or less likely if it is inhibitory.
Synaptic connections are signals that allow neurons (nerve cells) to connect and pass from one to the other, within the cerebral cortex of the brain. It allows the baby to develop color vision, pincer grasp, or a strong attachments with parents.
The neuronal systems are composed of neurotransmitters and the receptors. Neurons are the basic building structures of the neuronal systems. Nerve signals are sent out from one neuron to another through the Neurotransmitters. These neurotransmitters can either be excitatory or inhibitory. The excitatory neurotransmitters are the ones that broadcast a message to other neurons while the inhibitory neurotransmitters are the ones that keep the messages from being sent or received. Based on these received messages, the neurotransmitters then bind with the receptor sites on nerve synapses. There are a myriad of different neuronal systems in the brain. The different types of smart drugs (discussed above) interact with the different neuronal systems and help boost the efficiency of these systems leading to improved cognitive

Human brain consists of billions of cells interconnected together, with each performing its separate functions. It consists of two explicit categories of nerves: neurons and glia cells. Neuron is a single nerve cell in the entire nervous system; which is electrically excitable cell that carries information after being processed via chemical or electrical signals. One of its key characteristics is that it does not undergo cell division. In addition, it maintains a voltage gradient for all the neurons across its membranes. Glia cells, on the other hand, its functionality is to maintain homeostasis.
Nerve cells generate electrical signals to transmit information. Neurons are not necessarily intrinsically great electrical conductors, however, they have evolved specialized mechanisms for propagating signals based on the flow of ions across their membranes.
The individual cells within the brain, the neurons, release a whole array of chemical signals in communication with one
The NITRC 1000 Functional Connectomes Project and the Human Connectome Project have recently made large amounts of human connectome data available for public research in the form of connectivity matrices. These data have been extensively analyzed with respect to their network topology, which has revealed a number of complex network properties, including small-world and scale-free characteristics and high modularity and clustering. However, these studies have been conducted almost exclusively on binarized networks generated by thresholding to remove negative edge weights associated with negative temporal correlations in fMRI data. The present study proposes a comparison of the characteristics of networks generated exclusively from either
You live and you learn, from the moment that we breathe our first breath, we are assimilating and are acquiring information. Life changing and profound learning experiences happen before we can even speak, as children our learning process is grandiose. Harvard University published a series of summaries on Child development. One of these articles mentions that “The basic architecture of the brain is constructed through an ongoing process that begins before birth and continues into adulthood.” ("InBrief: The Science of Early Childhood Development," n.d.).
In our brain daily functions, the neurons transmit messages from one and other in the form of neurotransmitters, a chemical reaction
