Summary: Neuronal dynamics are influenced by short-term plasticity (STP), which can be dominated by short-term depression (STD), short-term facilitation (STF), or both. This study develops a network model with excitatory and inhibitory neurons endowed with STD and STF, mimicking the connectivity circuitry in the visual cortex. The results suggest that depression and facilitation are involved in switching between different activity patterns, and critical levels of depression and facilitation determine the network's behavior.

Summary: The NMDAR-based short-term postsynaptic plasticity (STPP) has been shown to have an impact on the dynamics of neural populations. Incorporating STPP into a continuous attractor neural network (CANN) model enhances the network's mobility and predictive capabilities.

Summary: Stimulation of the intralaminar thalamus in epilepsy patients led to increased broad gamma power and decreased alpha power in cortical EEG signals, suggesting enhanced cortical activation and arousal/attention. The findings support the therapeutic effects of intralaminar thalamic stimulation and warrant further investigations into optimal stimulation parameters for clinical improvements.

Summary: This study presents a biologically-plausible computational model that demonstrates the crucial role of hippocampal-thalamic-cortical activity in systems consolidation. The model provides testable predictions for experimental neuroscience and sheds new light on the mechanisms of memory engram reorganization and associated pathways.

Summary: Neuronal ensembles, identified as coactive groups of neurons in cortical activity, can last for weeks in the visual cortex of awake mice, with some ensembles maintaining activity for up to 46 days and displaying stronger functional connectivity.

Summary: The study found that slow cortical potentials and respiration are both coupled with the amplitude of fast neuronal oscillations, with stronger coupling during sleep. The phases of ISF and respiration drive the amplitude dynamics of fast oscillations in both sleeping and waking states, with different contributions.

Summary: This study reveals the interaction between thalamic activity and Cajal-Retzius cells (CRc) in the construction of the cortical layer 1 (L1). Thalamic activity and NMDA receptors regulate the early density of CRc, which in turn affects the distribution of upper layer interneurons and excitatory synapses, resulting in a significant impact on the activity of output pyramidal neuron dendrites.

Summary: The study identified the transcriptional mechanisms occurring in the VP following drug exposure and the important role of Nr4a1 in cocaine-related behaviors. Overexpression of Nr4a1 enhanced drug-seeking and drug-induced reinstatement, while Nr4a1 knockdown prevented self-administration acquisition and subsequent cocaine-mediated behaviors, highlighting the crucial role of the VP -> MDT circuit in drug intake and relapse-like behaviors.

Summary: The olfactory bulb and higher processing areas are interconnected synaptically, allowing for rapid regulation of circuit dynamics. Short-term plasticity changes at these synapses can modulate sensory processing. The granule cells in the olfactory bulb play a key role in mediating cortical feedback modulation and are subject to robust endocannabinoid modulation. Activation of the CB1 receptor modulates inhibitory synaptic currents and short-term depression, affecting the balance of cortical feedback excitation and inhibition of granule cells.

Summary: A brief period of monocular deprivation induces short-term plasticity of the adult visual system. The impact of MD on neural correlates of multisensory processes is assessed. Results reveal eye-specific changes in neural activities associated with visual and multisensory processes. MD increases excitability to visual events for the deprived eye and audio-visual and auditory input for the non-deprived eye.

Summary: Combined transcranial magnetic stimulation and electroencephalography (TMS-EEG) was used to investigate changes in cortical activity in patients with Parkinson's disease (PD) following multidisciplinary intensive rehabilitation treatment (MIRT). The results demonstrated improved motor and non-motor symptoms in responsive patients, with correlations between cortical power and clinical symptoms.

Summary: By surveying coral individuals in Australia and Japan from 2016 to 2019, this study explores the spatial variation in the short- and long-term dynamics of competitive, stress-tolerant, and weedy coral assemblages and how abiotic variability affects their structural composition. The study finds that coral assemblages can reduce their vulnerability to stochastic environments by focusing on short-term potential, but competitive coral taxa have a reduced ability to elevate their short-term potential compared to stress-tolerant and weedy assemblages. Future climatic shifts may threaten the structural complexity of coral assemblages in variable environments.

Summary: In southcentral Alaska, 31 short-term slow slip events (S-SSEs) were detected using Global Navigation Satellite System data. These events mainly occurred at a depth of 35 to 45 km, correlating with the down-dip extension of the 1964 Alaska earthquake and the subducting Yakutat microplate. The findings highlight the importance of short-term slow slip events for understanding interplate slip kinematics in this region.

Summary: This study reveals that the cortico-basal ganglia-thalamo-cortical (CBTC) circuit in mice supports the formation of selective persistent activity, shedding light on the underlying mechanisms of short-term memory. Optogenetic activation or inactivation of the basal ganglia output nucleus substantia nigra pars reticulata (SNr)-to-thalamus pathway biased future licking choice, without affecting execution, indicating a crucial role in decision-making processes.
