AI Article Synopsis

  • The study of human working memory (WM) is crucial in neuroscience, but investigating the medial temporal lobe (MTL) has been challenging due to noninvasive method limitations.
  • Recent advancements in intracranial neural recordings reveal that various MTL regions play unique roles in different aspects of WM and interact with each other and the wider brain network.
  • These findings suggest that the MTL should be included in models of WM to better capture the complex neural mechanisms of WM, which could improve our understanding of its flexibility, adaptability, and precision.

Article Abstract

The study of human working memory (WM) holds significant importance in neuroscience; yet, exploring the role of the medial temporal lobe (MTL) in WM has been limited by the technological constraints of noninvasive methods. Recent advancements in human intracranial neural recordings have indicated the involvement of the MTL in WM processes. These recordings show that different regions of the MTL are involved in distinct aspects of WM processing and also dynamically interact with each other and the broader brain network. These findings support incorporating the MTL into models of the neural basis of WM. This integration can better reflect the complex neural mechanisms underlying WM and enhance our understanding of WM's flexibility, adaptability, and precision.

Working memory processes and the histamine-3 receptor in schizophrenia: a [C]MK-8278 PET-fMRI study.

Psychopharmacology (Berl)

Rationale: Working memory impairment is a prominent feature of schizophrenia which predicts clinical and functional outcomes. Preclinical data suggest histamine-3 receptor (H3R) expression in cortical pyramidal neurons may have a role in working memory, and post-mortem data has found disruptions of H3R expression in schizophrenia.

Objectives: We examined the role of H3R in vivo to elucidate its role on working memory impairment in schizophrenia.

Anti-seizure medications and deep brain stimulation are widely used therapies to treat seizures; however, both face limitations such as resistance and the unpredictable nature of seizures. Recent advancements, including responsive neural stimulation and on-demand drug release, have been developed to address these challenges. However, a gap remains, as electrical stimulation provides only transient effects while medication has a delayed onset.

Identifying angiotensin-I-converting enzyme (ACE) inhibitory peptides accurately is crucial for understanding the primary factor that regulates the renin-angiotensin system and for providing guidance in developing new potential drugs. Given the inherent experimental complexities, using computational methods for in silico peptide identification could be indispensable for facilitating the high-throughput characterization of ACE inhibitory peptides. In this paper, we propose a novel deep stacking-based ensemble learning framework, termed Deepstack-ACE, to precisely identify ACE inhibitory peptides.

Hypothyroidism is known to affect memory consolidation, and our prior research highlighted the potential of chrysin as a therapeutic agent to restore cognitive function. The present study aimed to investigate the action mechanism of chrysin on memory deficits in hypothyroid in C57BL/6 female mice. We assessed cognitive flexibility, declarative, working, and aversive memories while analyzing the BDNF/TrkB/AKT/Creb neuroplasticity signaling pathway and synaptic function in the hippocampus and prefrontal cortex.

Electrical status epilepticus in sleep (ESES) is an electrographic pattern associated with cognitive impairment. Our study aimed to prospectively evaluate the psychiatric findings and language skills in patients diagnosed with ESES and to determine the immune modulatory treatment-responsive subgroups. We assessed the patients for psychiatric features and language skills at the baseline and 12 months after.
