Increase in hippocampal theta oscillations during spatial decision making
The processing of spatial and mnemonic information is believed to depend on hippocampal theta oscillations (5-12 Hz). However, in rats both the power and the frequency of the theta rhythm are modulated by locomotor activity, which is a major confounding factor when estimating its cognitive correlates. Previous studies have suggested that hippocampal theta oscillations support decision-making pr...
متن کاملEvent-related theta and alpha oscillations mediate empathy for pain.
Our recent event-related potential (ERP) studies showed that phase-locked electrophysiological activities mediate both early emotional sharing and late cognitive evaluation during empathy for pain. However, whether non-phase-locked neural oscillations are involved in empathic responses remains unknown. To investigate the functional role of non-phase-locked theta (3-8 Hz) and alpha (9-14 Hz) osc...
متن کاملDecision Making and Reward in Frontal Cortex
Patients with damage to the prefrontal cortex (PFC)--especially the ventral and medial parts of PFC--often show a marked inability to make choices that meet their needs and goals. These decision-making impairments often reflect both a deficit in learning concerning the consequences of a choice, as well as deficits in the ability to adapt future choices based on experienced value of the current ...
متن کاملEEG oscillations and recognition memory: theta correlates of memory retrieval and decision making.
Studies of memory retrieval have identified electroencephalographic (EEG) correlates of a test item's old-new status, reaction time, and memory load. In the current study, we used a multivariate analysis to disentangle the effects of these correlated variables. During retrieval, power of left-parietal theta (4-8 Hz) oscillations increased in proportion to how well a test item was remembered, an...
متن کاملDissociation between dorsal and ventral hippocampal theta oscillations during decision-making.
Hippocampal theta oscillations are postulated to support mnemonic processes in humans and rodents. Theta oscillations facilitate encoding and spatial navigation, but to date, it has been difficult to dissociate the effects of volitional movement from the cognitive demands of a task. Therefore, we examined whether volitional movement or cognitive demands exerted a greater modulating factor over ...
