Neuroscience bulletin · Cocaine Hijacks the Npas4-dependent Somatostatin Ensembles in the mPFC to Mediate Attention
研究發現單次可卡因注射會增加小鼠mPFC中Npas4轉錄依賴性神經元群體(N-RAM)及其與生長抑素互通神經元(N-RAM+ SST-IN)的共同激活,此機制促進來自中背丘的興奮性突觸輸入。抑制這些神經元群體會損害5選擇序列反應時間任務中的注意力表現,揭示其在可卡因導致注意缺陷中的關鍵角色。
eNeuro · GluN2A Enables Noradrenergic Control of Prefrontal Oscillations and Cognitive Flexibility
研究證明GluN2A含NMDA受體對於藍斑(LC)到mPFC的去甲腎上腺素輸入調節網絡振盪(尤其gamma頻段)及反轉學習是必要的。GluN2A缺失會導致振盪反應消失,並伴隨前調皮質中LC軸突密度增加與去甲腎上腺素轉運蛋白上調,提示發育性補償機制。此結果支持α2-腎上腺素受體路徑為改善前額葉網絡協調的治療標的。
Journal of computational neuroscience · Computational modeling of prefrontal-amygdala circuits links functional connectivity alterations to circuit-level mechanisms in major depression
利用改良的Jansen-Rit神經質量模型結合靜態fMRI功能連通性數據,研究模擬了前額葉-杏仁核電路在健康與抑鬱狀態下的動態。結果顯示,在健康狀態下杏仁核透過底向調節維持穩定並支持情緒調節;而在抑鬱狀態下,杏仁核過度激活會抑制腹內側前額葉並激活前扣帶皮質前部,導致認知調節與情緒失衡的異常電路狀態。此模型提供了一種機制性框架來理解功能連通性改變如何導致抑鬱症狀。
Journal of physical activity & health · Parent-Reported 24-Hour Movement Behaviors Movement Behaviors for Preschool Children: Evidence From Iraq
在伊拉克學前兒童(4-6歲)中,家長報告的中等至劇烈身體活動(MVPA)與睡眠時長與執行功能(經Head-Toes-Knees-Shoulders Revised任務測量)顯著正相關,而久坐行為與休閒螢幕時間則顯著負相關。組成數據分析進一步證實,相對於其他行為的MVPA比例以及相對於清醒時的睡眠比例,是預測更佳執行功能的獨立因子。此結果強調了在早期兒童發展中,平衡的24小時行為模式對執行功能的重要性。
Neuroreport · Frequency-dependent alterations of degree centrality in patients with poststroke depression: a resting-state functional MRI study
中風後抑鬱(PSD)患者在右側背外側前額葉皮質(DLPFC)於傳統、slow-4及slow-5頻帶均表現出持續降低的度中心性;而在slow-4頻帶中,左側DLPFC度中心性降低與自評抑鬱量表分數負相關,而左側蒼白球度中心性升高則與抑鬱嚴重程度正相關。此外,PSD組在slow-4帶中左側顳葉中迴、梭狀迴及胼胝體顯著增加度中心性。結果顯示slow-4帶為PSD中功能連通性異常最顯著的頻帶,提供了頻率特異性的神經生物標的。
