Involuntary memories (or flashbacks) are elicited in the participant by reading an emotionally charged script to them that is designed to trigger a flashback in individuals who suffer from PTSD. The investigators record the regions of the brain that are active during each of these conditions, and then subtract the activity.
Recall is made easier since the association the brain can make is between words and sounds spoken. A distinguishing feature is how males and females process information and then recall what was presented to them. Females tend to remember nonverbal cues and associate the meaning of a discussion with gestures. [58]
The temporal lobes are a region of the cerebral cortex that is located beneath the Sylvian fissure on both the left and right hemispheres of the brain. [14] Lobes in this cortex are more closely associated with memory and in particular autobiographical memory. [15] The temporal lobes are also concerned with recognition memory.

Brain regions involved in the 'what' and 'where' of an event [ edit ] Cabeza et al. conducted a positron emission tomography (PET) scan study on a group of human test subjects to identify the brain regions involved in temporal memory, which is based on a linear progression of events.
View of left entorhinal cortex (red) from beneath the brain, with front of brain at top. Artist's rendering. The superficial layers – layers II and III – of EC project to the dentate gyrus and hippocampus: Layer II projects primarily to dentate gyrus and hippocampal region CA3; layer III projects primarily to hippocampal region CA1 and the subiculum.
Humans have two hippocampi, one in each hemisphere of the brain.They are located in the medial temporal lobe of the brain. In this lateral view of the human brain, the frontal lobe is at the left, the occipital lobe at the right, and the temporal and parietal lobes have largely been removed to reveal one of the hippocampi underneath.
Thus, other brain regions are capable of noticing unfamiliarity, but the perirhinal cortex is needed to associate the feeling with a specific source. [2] The perirhinal cortex also receives a large dopaminergic input and signals the rewards that are associated with visual stimuli [4]
