Humans with a high motor excitability have a better working memory than humans with a low excitability. By measuring the motor excitability, conclusions can be drawn as to the general cortical ...
Motor cortex excitability is reduced during freezing of upper limb movement in Parkinson’s disease
Whilst involvement of the motor cortex in the phenomenon of freezing in Parkinson’s disease has been previously suggested, few empiric studies have been conducted to date. We investigated motor cortex ...
Determining the central mechanisms involved in muscle fatigue is important from a physiological perspective and can also have relevant implications from an applied perspective when we refer to sports, ...
Neural excitability is not constant; it depends on the brain's internal state. Our results show that even identical neurons can respond differently depending on the time of day, governed by molecules ...
This study investigates neurophysiological mechanisms underlying corticospinal excitability and sensorimotor cortical activity in response to neuroplasticity-priming interventions. We use non-invasive ...
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 ...
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, ...
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 ...
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 - ...
Nearly 20 years ago, scientists developed ways to stimulate or silence neurons by shining light on them. This technique, known as optogenetics, allows researchers to discover the functions of specific ...
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 ...
