Event-related brain potentials in memory: correlates of episodic, semantic and implicit memory

Asymmetric hemispheric contribution to ERPs in associative memory indexes goal relevance and quantity of information

“…It is not yet clear, however, how laterality of event-related potentials (ERP) is related to explicit memory processing. Two lateralized effects show a remarkable consistency across studies: a late right frontal old/new effect during retrieval [1][2][3][4][5][6] and a left negativity followed by a sustained positivity during associative encoding [4,[7][8][9][10][11][12]. The next paragraphs will shortly outline the models put forward to explain these effects.…”

“…Recognition success was matched across conditions; critically, the information associated to the cues was not necessary to solve the old/new test, so that response selection was not affected. We expected an early left frontal effect during associative encoding, followed by a sustained positivity [4,[7][8][9]. We exploratively studied the ERP correlates of goal-unrelated encoding, aiming at establishing a link between electrophysiological activity during encoding and the right late frontal component during retrieval.…”

Staff's awareness of abuse in health care varies according to context and possibilities to act

“…According to modern memory research there are several memory subsystems (27). While the episodic memory is detailed and colorful, close to mental reliving, semantic memory contains general information without personal experiences (28).…”

Promovendo resiliência em vítimas de trauma psicológico

“…The level of consciousness and emotions modulate the memory formation, 12,22 and the multiple memory systems can be simultaneously activated and interact in several occasions. 20,21 According to neuroscience findings, the key-factor for the therapeutic reconstruction of traumatic memories relies on managing the consciousness states and emotions properly, in order to modify the modulation of the traumatic memory and, consequently, the relation with the past event. The psychological dynamics that frames the narrative of the traumatic memory can also change.…”

“…Multiple memory systems are simultaneously activated and can interact in several occasions. 20,21 This way, declarative memories (verbally accessible) together with resilient attitudes (ability to go through difficult periods and recover with satisfactory quality of life), such as learning with experiences, self-esteem, self-confidence and tranquility to face difficulties can be part of this huge repertoire and, consequently, participate in the process of memory reconstruction.…”
