AI Article Synopsis
- - Studies indicate that higher activation in the left prefrontal cortex (PFC) before exercise is linked to more positive psychological outcomes, including better mood and reduced anxiety.
- - A systematic review analyzed 1901 studies on this topic but narrowed it down to 8 relevant studies that met specific criteria involving EEG measurements and psychological assessments.
- - Most of the studies (75%) supported the idea that greater left PFC activation correlates with positive states like energetic arousal and calmness, while some studies showed varying levels of bias in their methodologies.
Article Abstract
Background: Studies have shown a relationship between prefrontal cortex (PFC) activation asymmetry and psychological responses to exercise, so that a higher rest activation in left rather than right PFC has been associated with positive psychological responses to exercise such as an improved affect, anxiety and multidimensional arousal states.
Purpose: To review: 1) evidence that PFC activation asymmetry before exercise is associated with psychological responses to exercise; 2) protocols of PFC asymmetry determination.
Methods: A systematic review (SR) was performed on studies retrieved from the PubMed and Web of Science database up to 04-30-2019. Eligibility criteria were: 1) studies investigating participants submitted to aerobic exercises; 2) including cerebral activation measures through electroencephalography (EEG) before the exercise bout; 3) and psychological measures during or after the exercise bout; 4) original studies.
Results: A number of 1901 studies was retrieved from the databases and 1 study was manually inserted. Thereafter, 1858 studies were excluded during the screening stage so that 30 studies remained for the SR. After full reading, 22 studies were excluded and 8 studies composed the final SR. Methodological assessment revealed that 62.5% of the studies showed a low risk of bias, while 34.37% and 3.12% showed either an unclear or a high risk of bias, respectively. Protocols of PFC activation asymmetry used EEG at F3-F4-P3-P4 (3 studies), F3-F4 (2 studies), F3-F4-T3-T4 (1 study), F3-F4-F7-F8-T5-T6-P3-P4 (1 study) and Fp1-Fp2-Fz-F3-F4-F7-F8-Cz-C3-C4-T3-T4-T5-T6-Pz-P3-P4-Oz-O1-O2 (1 study) positions. Most studies (75%) found a higher left PFC activation associated with a greater affect (n = 2), energetic arousal (n = 2), lower anxiety (n = 2) as well as calmness and tired arousal, simultaneously (n = 1).
Conclusions: Although the heterogeneity of PFC asymmetry protocols, reviewed studies showed a low risk of bias, suggesting that a higher left PFC activation is associated with a positive psychological response to exercise.

Transcriptomic Evidence Reveals the Dysfunctional Mechanism of Synaptic Plasticity Control in ASD.

Background/objectives: A prominent endophenotype in Autism Spectrum Disorder (ASD) is the synaptic plasticity dysfunction, yet the molecular mechanism remains elusive. As a prototype, we investigate the postsynaptic signal transduction network in glutamatergic neurons and integrate single-cell nucleus transcriptomics data from the Prefrontal Cortex (PFC) to unveil the malfunction of translation control.
Methods: We devise an innovative and highly dependable pipeline to transform our acquired signal transduction network into an mRNA Signaling-Regulatory Network (mSiReN) and analyze it at the RNA level.

Background: N-methyl-D-aspartate type glutamate receptors (NMDARs) are fundamental to neuronal physiology and pathophysiology. The prefrontal cortex (PFC), a key region for cognitive function, is heavily implicated in neuropsychiatric disorders, positioning the modulation of its glutamatergic neurotransmission as a promising therapeutic target. Our recently published findings indicate that AT receptor activation enhances NMDAR activity in layer V pyramidal neurons of the rat PFC.

Background: Innovative treatments for paranoia, which significantly impairs social functioning in schizophrenia (SCZ), are urgently needed. The pathophysiology of paranoia implicates the amygdala-prefrontal (PFC) circuits; thus, this study systematically investigated whether transcranial direct current stimulation (tDCS) to the ventrolateral PFC can attenuate paranoia and improve social functioning in SCZ.
Methods: A double-blind, within-subjects, crossover design was used to compare active vs.

Maintaining balance while simultaneously performing other tasks is common during everyday activities. However, this dual-tasking (DT) divides attention and increases cognitive demand, which can be detrimental to stability in older adults. It is unknown if the focus of attention influences how a dual-task affects balance and whether this is detectable in middle-aged adults.
