Social anxiety disorder (SAD) is associated with aberrant emotional information processing while little is known about non-emotional cognitive processing biases. The dorsal anterior cingulate cortex (dACC) has been implicated in SAD neuropathology and is activated both by emotional and non-affective cognitive challenges like the Multisource Interference Task (MSIT).

Repeated exposure to stress (chronic stress) can cause excess levels of circulating cortisol and has detrimental influences on various cognitive functions including long-term memory and navigation.
Differential effects of exposure to toxic or nontoxic mold spores on brain inflammation and Morris water maze performance
Cheryl F. Harding a,b,*, David Liao a,c, Ramona Persaud a,c,d, Richard A. DeStefano c,d, Kimberly G. Page b, Lauren L. Stalbow c,f, Tina Roa e, Jordan C. Ford e, Ksenia D. Goman a, Carolyn L. Pytte

Volume 442, 28 March 2023, 114294
People who live or work in moldy buildings often complain of “brain fog� that interferes with cognitive performance. Until recently, there was no published research on the effects of controlled exposure to mold stimuli on cognitive function or an obvious mechanism of action, fueling controversy over these claims.
Mirtazapine modulates Glutamate and GABA levels in the animal model of maternal depression. MRI and 1H MRS study in female rats
Marianna Makov Ì�a a, Svatava Kaˇsparov Ì�a a,*, Tom Ì�aˇs TvrdÃk a,b, Mireia Noguera c, KristÃna Beloviˇcov Ì�a c, KristÃna Csatlosov Ì�a c, Michal Dubovický

Volume 442, 28 March 2023, 114296
We aimed to determine, using in vivo magnetic resonance, whether maternal depression induced by chronic unpredictable stress (CUS) in the pre-gestational period in female rats would be evidenced by structural or neurometabolic changes in the hippocampal region of the brain.
β-adrenoceptors of the infra-limbic cortex mediate corticosterone-induced enhancement of acquisition and consolidation of fear memory extinction in rats

The extinction of auditory fear conditioning (AFC) refers to reducing the fear responses induced following repeated presentation of a conditioned stimulus (tone) in the absence of an unconditioned stimulus (electric foot shock).
Investigation of neurobiological responses to theta burst stimulation during recovery from mild traumatic brain injury (mTBI)
Hannah L. Coyle a,1, Neil W. Bailey a,b,c,*,1, Jennie Ponsford d,e, Kate E. Hoy a,
doi : 10.1016/j.bbr.2023.114308
Volume 442, 28 March 2023, 114308
The ability of the brain to recover following neurological insult is of interest for mild traumatic brain injury (mTBI) populations. Investigating whether non-invasive brain stimulation (NIBS) can modulate neurophysiology and cognition may lead to the development of therapeutic interventions post injury.
Diabetes influences the fusion of autophagosomes with lysosomes in SH-SY5Y cells and induces Aβ deposition and cognitive dysfunction in STZ-induced diabetic rats
Lou-Yan Ma a, Song-fang Liu b, Ya-gang Guo c, Zheng-quan Ma a, Ya Li d, Shu-jin Wang b, Yu Niu b, Mo Li a, Jia-jia Zhai a, Su-hang Shang e, Ya-Li Lv f,*, Qiu-Min Qu

Volume 442, 28 March 2023, 114286
Diabetes has been regarded as an independent risk factor for Alzheimer’s disease (AD). Our previous study found that diabetes activated autophagy, but lysosome function was impaired. Autophagy-lysosome dysfunction may be involved in Aβ deposition in diabetic cognitive impairment.
Sub-chronic administration of fluoxetine does not alter prey-capture or predator avoidance behaviors in adult South African clawed frogs (Xenopus laevis).

Volume 442, 28 March 2023, 114317
Animals will halt foraging efforts and engage defensive behaviors in response to predator cues. Some researchers have proposed that the switch from appetitive to avoidance behavior resembles anxiety, but most work on this has been performed in a limited number of animal models, primarily zebrafish and rodents.
Long-term sevoflurane exposure resulted in temporary rather than lasting cognitive impairment in Drosophila

Volume 442, 28 March 2023, 114327
Sevoflurane is the primary inhaled anesthetic used in pediatric surgery. It has been the focus of research since animal models studies found that it was neurotoxic to the developing brain two decades ago.
Increased depressive-like behaviour of postpartum Flinders sensitive and resistant line rats is reversed by a predictable postpartum stressor

During the peripartum period, women are at an increased risk to develop perinatal distress, presenting as symptoms of depression and/or anxiety. Yet, due to practical and ethical restrictions, our understanding of this condition remains limited.
Effects of sex and pro-inflammatory cytokines on context discrimination memory

In learning and memory tasks, immune overactivation is associated with impaired performance, while normal immune activation is associated with optimal performance. In one specific domain of memory, context discrimination memory, peripheral immune stimulation has been shown to impair performance on the context-object discrimination memory task in male rats.
Abdominal surgery plus sevoflurane exposure induces abnormal emotional changes and cognitive dysfunction in aged rats
Jin-Meng Lv a,1, Li-Min Zhang b,*,1, Jie-Xia Wang c, Jing-Jing Shao d, Xin-Gui Guo e, Lu-Ying Wang f, Li-Qing Kang g, Wei-Chao Zheng h, Yue Xin i, Rong-Xin Song j, Wei Guo k, Dong-Xue Zhang

Volume 442, 28 March 2023, 114328
Cognitive impairment, which includes perioperative psychological distress and cognitive dysfunction, can be determined by preoperative and post-operative neuropsychological tests.
Matrix metalloproteinase-9 overexpression in the hippocampus reduces alcohol-induced conditioned-place preference by regulating synaptic plasticity in mice
Li-Tian Yin a,*,1, Rui-Rui Feng a,1, Xiao-Yan Xie a, Xiao-Rong Yang a, Zhuan-Fang Yang a, Jia-Jia Hu a, Shu-Fen Wu a,b, Ce Zhang

Extracellular matrix proteins appear to be necessary for the synaptic plasticity that underlies addiction memory. In the brain, matrix metalloproteinases (MMPs), especially matrix metalloproteinase-9 (MMP-9), have been recently implicated in processes involving alcohol reward and memory.
Baicalin facilitates remyelination and suppresses neuroinflammation in rats with chronic cerebral hypoperfusion by activating Wnt/β-catenin and inhibiting NF-κB signaling
Yining Xiao a,b,c, Tianyuan Guan a,b, Xiaofeng Yang a,d, Jing Xu b,c, Jiawei Zhang a, Qianqian Qi a,b, Zhenjie Teng a,b,c, Yanhong Dong b,c, Yaran Gao b, Meixi Li b, Nan Meng b, Peiyuan Lv

One main factor contributing to the cognitive loss in vascular dementia (VD) is white matter lesions (WMLs) carried on by chronic cerebral hypoperfusion (CCH). A secondary neuroinflammatory response to CCH accelerates the loss and limits the regeneration of oligodendrocytes, leading to progressive demyelination and insufficient remyelination in the white matter.
Chronic stress beginning in adolescence decreases spatial memory following an acute inflammatory challenge in adulthood

Volume 442, 28 March 2023, 114323
Prolonged stress beginning in adolescence can contribute to the dysregulation of the neuroendocrine system in adulthood. As the neuroendocrine and neuroimmune systems participate in bi-directional regulatory control, adolescent stress can prime the neuroimmune system to future inflammatory insults.

Volume 442, 28 March 2023, 114309
We are witnessing a considerable increase in the incidence of Parkinson’s disease (PD), which may be due to the general ageing of the population.
