Transcranial magnetic stimulation (TMS) has the potential to yield insights into cortical functions and improve the treatment of neurological and psychiatric conditions. However, its reliability is hindered by a low reproducibility of results. Among other factors, such low reproducibility is due to structural and functional variability between individual brains.

Following cerebral ischemia, reperfusion injury can worsen ischemia-induced functional, metabolic disturbances, and pathological damage upon blood flow restoration, potentially leading to irreversible harm. Yet, there's a dearth of advanced, localized drug delivery systems ensuring active pharmaceutical ingredient (API) efficacy in cerebral protection during ischemia-reperfusion. This study introduces a multivalent bioadhesive nanoparticle-cluster, merging bioadhesive nanoparticles (BNPs) with dendritic polyamidoamine (PAMAM), enhancing nose-to-brain delivery and brain protection efficacy against cerebral ischemia-reperfusion injuries (CIRI).

Local field potential (LFP) recordings using chronically implanted sensing-enabled stimulators are a powerful tool for indexing symptom presence and severity in neurological and neuropsychiatric disorders, and for enhancing our neurophysiological understanding of brain processes. LFPs have gained interest as input signals for closed-loop deep brain stimulation (DBS) and can be used to inform DBS parameter selection. LFP recordings using chronically implanted sensing-enabled stimulators have various implementational challenges.

Deep learning tools applied to high-resolution neurophysiological data have significantly progressed, offering enhanced decoding, real-time processing, and readability for practical applications. However, the design of artificial neural networks to analyze neural activity in vivo remains a challenge, requiring a delicate balance between efficiency in low-data regimes and the interpretability of the results. Approach: To address this challenge, we introduce a novel specialized transformer architecture to analyze single-neuron spiking activity.

Recent strides in neurotechnology show potential to restore vision in individuals afflicted with blindness due to early visual pathway damage. As neuroprostheses mature and become available to a larger population, manual placement and evaluation of electrode designs becomes costly and impractical. An automatic method to optimize the implantation process of electrode arrays at large-scale is currently lacking.
