Summary: Stimulating a single neuron in the rat somatosensory cortex can elicit a behavioral response, contrary to the assumption that only a large group of neurons can control behavior. The probability of a behavioral response increases significantly with irregular current injection, and a circuit approximating a differentiator can reliably detect single-cell stimulation, in agreement with experimental findings.

Summary: The synchronized and balanced electrical activity of neurons is crucial for the brain to process information, learn, and remember. In Alzheimer's disease, cognitive decline is caused by the disruption of this synchronization and balance due to the accumulation of neuropathological biomarkers such as A842, which impairs crucial neuronal classes and cognitive brain rhythms. The use of recombinant BRICHOS molecular chaperone domains shows promise in rescuing the disruption of cognition-relevant brain rhythms in AD.

Summary: This study presents a Bayesian approach to mapping neuron connectivity in the striatum. By applying it to the mouse striatum, two asymmetries in the circuit were discovered: a selective asymmetry of projection neuron connections and a length-scale asymmetry. The Bayesian approach can also evaluate evidence for wiring changes, making it significant for understanding the function and dysfunction of the striatum.

Summary: This study revealed that histone acetylation regulates hippocampal gamma oscillations by modulating the activity of fast spiking interneurons, and the deficits in gamma oscillations in AD model mice can be restored by HDAC inhibitor or NR4a activator. These findings suggest a potential therapeutic target for treating cognitive impairment in AD patients.

Summary: The brain relies on the ability of the neocortex to integrate sensory information with internal signals in order to make quick adjustments to behavior, with pyramidal cells in layer 1 playing a crucial role. Layer 1 serves as the primary input layer for top-down information, contributing to functions such as sensory perception, cross-modal integration, controlling states of consciousness, attention, and learning.

Summary: In a model of ALS, it has been found that motor neurons receive stronger inhibitory synaptic inputs than slow motor neurons, and disease progression is associated with specific loss of inhibitory synapses onto fast motor neurons.

Summary: The neuroinflammation factor galectin-3 (gal3) disrupts neuronal network oscillations in Alzheimer's disease (AD). Gal3 application decreases gamma oscillation power and rhythmicity, impairing cellular dynamics and inducing a collapse in network performance. Inhibition of gal3 may be a potential therapeutic strategy for treating AD and other neuroinflammatory disorders.

Summary: This study investigates the effects of low doses of ketamine on neural activity in the auditory cortex of rats. It finds that ketamine significantly increases rhythmic signals and adjusts network synchrony in the auditory cortex, which is modulated by the animal's motor state and may be related to the involvement of fast-spiking interneurons.

Summary: By visualizing the somas and dendrites of PV neurons in transgenic mice, this study clarified the specific connectivity between PV neurons and pyramidal neurons in the cortical circuits. The results showed that layer 6 CT-like pyramidal neurons formed more appositions to PV neurons compared to other pyramidal neurons, preferentially in layers 5b-6. Furthermore, layer 6 CT-like and corticocortical-like neurons formed compound appositions more frequently than other pyramidal neurons. This study suggests that layer 6 CT neurons play a role in intracortical information processing through their connections with PV neurons in layers 5b-6.

Summary: The study focused on the modulation of upper ocean vertical temperature structure after fast-moving tropical cyclones in the northern South China Sea. The effects of mixing and vertical advection on upper ocean temperature and heat response were examined. A parameterization approach based on mixing depth, transition layer thickness, and upwelling depth was able to reproduce sea surface temperature and upper ocean heat change. The study also highlighted how TC-induced mixing and advection influence the ocean heat budget.

Summary: Estrogens play a role in promoting the function of cholinergic neurons and have an impact on cognitive function. This study found that ovariectomy reduces the expression of cholinergic synaptic proteins in the entorhinal cortex, and this reduction can be prevented by estradiol replacement. Ovariectomy also impairs the cholinergic modulation of excitatory transmission in the entorhinal cortex, which may be related to the changes in cholinergic proteins.

Summary: This study uses in vivo two-photon functional imaging to investigate the role of A24b/M2-V1(axons) in visual selective attention in mice. The results suggest that the activity of these axons is associated with licking behavior, modulated by reward, and biased toward the sensory cortical hemisphere representing the currently discriminated stimulus.
