Contributions Of the Human Medial Prefrontal Cortex To Associative Recognition Memory: Evidence From Functional Neuroimaging
… have predominantly focused their attention on medial temporal lobe (MTL). There is growing acknowledgement however, from the cognitive neuroscience of memory literature, that regions outside the MTL can support episodic memory processes. The medial prefrontal cortex is one such region garnering …

The effects of repeated amphetamine exposure during adolescence on behavior and prefrontal cortex function
… receptor function, and prefrontal cortex (PFC) activity, with a focus on the consequences of drug exposure during adolescence. Chapter 1 includes a review of the literature on substance abuse and PFC dysfunction along with the specific aims of the studies described in the following …

THE RELATIONSHIP BETWEEN P300 EVOKED POTENTIALS AND PREFRONTAL CORTEX OXYGEN USE: A COMBINED EEG AND NIRS STUDY
… has also indicated increased prefrontal cortex (PFC) activity during P300 generation. To examine the relationship between P3b amplitude and PFC activity participants performed an easy and difficult target detection task in both EEG and NIRS called the oddball. The EEG and behavioral results …

The role of reuniens and rhomboid thalamic nuclei in spatial memory
… for this process are prefrontal cortex (PFC) and hippocampus. The hippocampus has strong connections to medial PFC, however there are no direct return projections from medial PFC to hippocampus. The reuniens (Re) and rhomboid (Rh) nuclei of ventral midline thalamus have anatomical …

Top-down and Bottom-up influences on ACC activation: Evaluation of a proposed model of the feedback-related negativity
… which includes direct modulating influences of medial PFC (i.e., top-down signals) on the ACC at the time of the FRN. Study 1 examined the effects of one’s sense of control (top-down) and of informative cues (bottom-up) on the FRN measures. In Study 2, sense of control and instruction-based …

PREFRONTAL CORTEX ACTIVITY DURING ATTENTIONAL BIAS CONDITIONING WITH FEARFUL FACES: A NEAR-INFRARED SPECTROSCOPY ANALYSIS
… hemodynamic responses in the prefrontal cortex (PFC) were measured using near-infrared spectroscopy (NIRS). It was hypothesized that after pairing a neutral stimulus (a colored square) with a fearful face, attentional bias toward the fearful face would transfer to the neutral stimulus. It was …

The role of frontal-striatal circuits in instrumental behaviour
… homologies that exist for the prefrontal cortex (PFC). A novel touchscreen-based contingency degradation task was developed for the common marmoset monkey, a New World non-human primate. The possible roles of the primate medial PFC (area 32), anterior cingulate cortex (area 24), ventromedial PFC …

Identifying the Neural Correlates of Motor Sequence Learning and Movement Automaticity
… on the stage of learning. The prefrontal cortex (PFC), in particular, has been observed at the early/fast phase and late/slow phase of motor sequence learning, suggesting involvement in processes such as movement automaticity, stimulus-response conflicts, explicit learning, and retrieval, to name …

Repeated amphetamine exposure and the enduring consequences on behavioral and neural plasticity
… methods very sensitive to prefrontal cortex (PFC) function. In experiment 1 (Chapter 5), single-unit recordings from actively behaving rats were used to examine the relationship between the locomotor response (i.e., the ability to induce sensitization) and medial PFC (mPFC) firing activity to …

The development and evaluation of the Cognitive Behavioural Social Competence Therapeutic Intervention for Adults with Autism Spectrum Disorder without an Intellectual Disability (CBSCTI-ASD)
… in cortical regions of the Prefrontal Cortex (PFC), an area associated with the social brain. The aim of study 2 was to assess functional regions of the social brain and evaluate the possible neurological effects of CBSCTI-ASD. While applying fNIRS to measure neural functioning, the five …
