Brain cells can be broadly divided into two categories: inhibitory and excitatory neurons. Excitatory neurons are cells that support the generation of electrical impulses in postsynaptic neurons, thus prompting the activation ...
The brain creates a map of our environment, which enables reliable spatial navigation. The Nobel Prize was awarded in 2014 for research into how this navigation system works at the cellular level. Researchers at the Medical ...
