A new study shows that direct stimulation of memory-relevant brain areas can enhance memory performance, but only when stimulation is applied during brain states associated with poor memory outcome - stimulation during optimal states results in a decrease in memory.

The effects of pharmacological interventions on fear memory have widely been studied, but there are very few studies about the effects of brain electrical stimulation on fear memory function.
Transcranial alternating current stimulation (tACS) is a promising tool for noninvasive investigation of brain oscillations. TACS employs frequency-specific stimulation of the human brain through curr...
Non-invasive brain stimulation (NIBS) has been gaining increased popularity in human neuroscience research during the last years. Among the emerging NIBS tools is transcranial electrical stimulation (...
Insulin action in the human brain influences eating behavior, cognition, and whole-body metabolism. Studies investigating brain insulin rely on intranasal application.
Adaptive deep brain stimulation uses feedback about the state of neural circuits to control stimulation rather than delivering fixed stimulation all the time, as currently performed. In patients with ...
Background: Alzheimer disease (AD) is a debilitating brain disorder that affects over 4.75 million people in the US and Canada. People with AD have difficulty remembering general facts and...
The beneficial effect of nocturnal as well as daytime sleep on memory consolidation is well-documented in young, healthy subjects. Slow wave sleep (SWS), in particular, with its slow oscil...
The beneficial effect of nocturnal sleep on memory consolidation is well-documented in young, healthy subjects. Especially, periods rich in slow-wave sleep (SWS) have shown a memory enhanc...
This project investigates the effects of repetitive transcranial magnetic stimulation (rTMS) on neural circuits as a function of spatiotemporal parameters and brain state in order to bette...
This is part of a larger study for which participants have already completed memory and thinking tests. In this study, investigators are trying to learn how deep-brain stimulation affects ...
Stimulation of the brain, which is self-administered. The stimulation may result in negative or positive reinforcement.
A persistent activity-dependent decrease in synaptic efficacy between NEURONS. It typically occurs following repeated low-frequency afferent stimulation, but it can be induced by other methods. Long-term depression appears to play a role in MEMORY.
A state of prolonged irreversible cessation of all brain activity, including lower brain stem function with the complete absence of voluntary movements, responses to stimuli, brain stem reflexes, and spontaneous respirations. Reversible conditions which mimic this clinical state (e.g., sedative overdose, hypothermia, etc.) are excluded prior to making the determination of brain death. (From Adams et al., Principles of Neurology, 6th ed, pp348-9)
Adjustment of BRAIN WAVES from two or more neuronal groups within or across a brain structure (e.g., cortical and limbic brain structures) to become uniform in EEG oscillation patterns in response to a stimulus. It is interpreted as a brain integration sign during many processes such as learning, memory, and perception and involves reciprocal neural connections.
Type of declarative memory, consisting of personal memory in contrast to general knowledge.
