Nerve cells can regulate their sensitivity to incoming signals autonomously. A new study has now discovered a mechanism that does just that. Nerve cells can regulate their sensitivity to incoming ...

In humans, who are mainly active during daylight hours, the capacity for learning and memory formation may peak during the twilight period approaching sunset. In other words, the best time to study or ...

Proceedings of the National Academy of Sciences of the United States of America, Vol. 106, No. 16 (Apr. 21, 2009), pp. 6760-6765 (6 pages) When neuronal activity is reduced over a period of days, ...

Researchers have devised a way to achieve long-term changes in neuron activity. With their new strategy, they can use light exposure to change the electrical capacitance of the neurons' membranes, ...

Nocturnal rats are active at night and accumulate fatigue toward dawn. Using optogenetic stimulation of cortical neurons and simultaneous local field potential (LFP) recordings, the study revealed ...

Our brains do not react in a fixed, mechanical way like electronic circuits. Even if we see the same scene every day on our commute to work, what we feel - and whether it leaves a lasting impression - ...

Peripheral sensitization refers to the lowering of the threshold of excitability of sensory neurons, which leads to an amplified reaction to a specific external stimulus. Sensitization can be mediated ...

This study investigates neurophysiological mechanisms underlying corticospinal excitability and sensorimotor cortical activity in response to neuroplasticity-priming interventions. We use non-invasive ...

This study investigates changes in spinal excitability using peripheral nerve stimulation. We use the Hoffman reflex (H-reflex) to assess segmental changes following a neuroplasticity-priming ...
