Libet Experiment
A famous 1980s experiment by neuroscientist Benjamin Libet in which participants reported the moment they consciously decided to move a finger, while brain activity called the readiness potential was recorded and found to begin measurably before that reported moment of conscious decision. It has been widely, and controversially, cited as evidence bearing on the existence and nature of free will, though its interpretation remains strongly disputed.
neuroscience · intro
Limbic System
A group of interconnected brain structures, including the amygdala, hippocampus, and hypothalamus, traditionally associated with emotion, motivation, and memory. While the term remains in wide use, contemporary neuroscience treats it as a useful but imprecise grouping rather than a single, sharply defined anatomical or functional system.
clinical-and-disorders · intermediate
Locked-In Syndrome
A rare condition, typically resulting from damage to the brainstem, in which a patient is fully conscious and cognitively intact but almost completely paralysed, retaining control of only very limited voluntary movement, such as vertical eye movements or blinking, which can sometimes be used to communicate. It is distinguished from disorders of consciousness by the patient's intact awareness, despite the near-total loss of motor output.
cognitive-science · intro
Long-Term Memory
The relatively permanent storage of information over extended periods, ranging from days to a lifetime, as distinguished from the brief, limited-capacity storage of working memory. It is commonly divided into explicit (consciously recollected) and implicit (unconsciously expressed) forms, and further into subtypes such as episodic, semantic, and procedural memory.
sleep-and-altered-states · intermediate
Lucid Dreaming
A state during REM sleep in which the dreamer becomes aware that they are dreaming, and in some cases can exert deliberate control over the content of the dream. It has been verified experimentally through pre-arranged eye-movement signals that lucid dreamers can perform on cue while their sleep stage is independently confirmed by brain monitoring.
