Human hippocampal processing of environmental novelty during spatial navigation
The detection and processing of novel information encountered as we explore our environment is crucial for learning and adaptive behavior. The human hippocampus has been strongly implicated in laboratory tests of novelty detection and episodic memory, but has been less well studied during more ethological tasks such as spatial navigation, typically used in animals. We examined fMRI BOLD activit...
متن کاملSpecific Motor Response during Sleep to Sleep-administered Meaningful Suggestion: an Exploratory Investigation.
--Complex meaningful suggestions were given during various stages of physiological sleep as defined by EEG monitoring to 4 Ss high and 4 Ss low in hypnotizability. All the high hypnotizability Ss gave accurate behavioral responses while remaining asleep, but none of the low hypnotizability Ss did so. Specific response to sleep-administered suggestion was obtained only during Stage 1 periods.
متن کاملERPs studies of cognitive processing during sleep.
In the last few decades, several works on cognitive processing during sleep have emerged. The study of cognitive processing with event related potentials (ERPs) during sleep is a topic of great interest, since ERPs allow the study of stimulation with passive paradigms (without conscious response or behavioural response), opening multiple research possibilities during different sleep phases. We ...
متن کاملCognitive processing during the transition to sleep.
Dramatic physiological and behavioural changes occur during the transition from wakefulness to sleep. The process is regarded as a grey area of consciousness between attentive wakefulness and slow wave sleep. Although there is evidence of neurophysiological integration decay as signalled by sleep EEG elements, changes in power spectra and coherence, thalamocortical connectivity in fMRI, and sin...
متن کاملSubconscious Stimulus Recognition and Processing During Sleep
During sleep, consciousness is reduced, associated with a diminished connection of the brain to the environment. This is due to the blocking of the thalamocortical pathway by inhibitory mechanisms. This “thalamic gating” during sleep, however, is not complete, but partial. The stream of information is considerably reduced, but the brain is not fully disconnected from the environment. An inspect...
