Most neurons have many branching extensions called dendrites that receive input from thousands of other neurons. Dendrites aren't just passive information-carriers, however. According to a new study from MIT, they appear ...

Neurons pass on information to one another via synapses. The vast majority of these synapses are excitatory, which increase the activity of the receiving neuron. Around 10 to 20 percent of synapses have the opposite effect, ...

Our actions are driven by "internal states" such as anxiety, stress or thirst—which will strongly affect and motivate our behaviors. Not much is known about how such states are represented by complex brain-wide circuits, ...

The speed of the human brain is remarkable—in a fraction of a second, neurons are activated, propagating thoughts and reactions to stimuli. But the speed at which we can noninvasively follow brain function using an MRI ...

Researchers from the Netherlands Institute for Neuroscience have found that the rat brain activates the same cells when they observe the pain of others as when they experience pain themselves. In addition, without the activity ...

When looking at a picture of a sunny day at the beach, we can almost smell the scent of sun screen. Our brain often completes memories and automatically brings back to mind the different elements of the original experience. ...

When we receive a stimulus, sensory information is transmitted by the afferent nerves to the thalamus, which in turn, like a relay, forwards the information to the sensory cortex to process it and consciously perceive the ...
