New Brandeis research sheds light on memory by erasing it
...that are necessary for a memory molecule. Like a computer
whose electronics change with the addition of new information, molecular activity in the hippocampus, where memory is stored in the brain, changes as memory is being stored. In this study, Lisman and his colleagues showed that they could saturate the...

Role of noise in neurons
... (1m is one millionth of a meter). Although, as in computer
chips, this miniaturization economizes on space and energy, it increases the noise introduced by thermodynamic fluctuations in a neuron's voltage-gated ion channels. Axons use action potential (AP) to transmit information fast and reliably to synapse...
