What does your brain really look like? It depends on how it's imaged. Take a look at all the different ways we can view the human brain.

Neurons are the structural and functional unit of our nervous system. They are the essential part of the communication system in our brain. ...
Find out what are the 3 different parts of a neuron and which part does what. Also learn about other important structures instrumental to neuron’s function
different types of neurons
A neuron is a nerve cell that processes and transmits information through electrical and chemical signals in the nervous system. Neurons consist of a cell body, dendrites (which receive signals), and an axon (which sends signals). Synaptic connections allow communication between neurons, facilitating the relay of information throughout the body.
With more than seventy neuron species in the small, but tightly structured retina, how many different kinds of neurons are there in the entire brain?
The evolving story of rapid changes in the brain with new synapses & neurons just added a new type of neuroplasticity involving changes in neurotransmitters
Every animal you can think of -- mammals, birds, reptiles, fish, amphibians -- all have brains. But the human brain is unique. It gives us the power to think, plan, speak and imagine.
Throughout the world, there are many different types of people, and their identity can tell a lot about where they live. The type of job they work, the kind of car they drive, and the foods they eat can all be used to predict the country, the state, or maybe even the city a person lives in.
The art of science: a network of nerve cells and a neural sunrise, captured under the microscope This stunning image shows a network of the nerve cells which carry sensory information from the world to your spinal cord and brain. A fluorescent dye highlights the fine nerve fibres, which reach out to carry signals from
The brain's complexity depends largely on the variety of its neuronal cell types, but what further functional heterogeneity exists within each class of neurons is still poorly documented. Focusing on the olfactory system, Troy Margrie and colleagues now report that mitral cells belonging to the same glomerulus — and therefore receiving input from one common odorant receptor — express similar levels of the HCN2 ion channel subunit, and thus present similar neuronal excitability. Mitral cells engaged in brain circuits linked to other glomeruli express different biophysical profiles, suggesting that intrinsic diversity among neurons of a given morphological class may reflect functional adaptations of local circuits to the subtly distinct information they process.
