Article Synopsis
- Researchers studied neuron organization in the macaque monkey's area V4, focusing on shape and texture selectivity using advanced Neuropixels probes on two awake monkeys.
- They found that about 20% of neurons formed clusters with similar tuning, but these clusters were limited to specific layers rather than showing a columnar structure throughout the cortex.
- The findings suggest that area V4's organization prioritizes broader stimulus categories and spatial scales, opposed to fine-tuned columnar arrangements seen in the primary visual cortex, highlighting the complexity of input integration in mid-level visual processing.
Article Synopsis
- Researchers studied the functional organization of neurons in macaque area V4, known for its role in processing visual forms and textures, using advanced Neuropixels probes on awake monkeys.
- They discovered that approximately 20% of neurons in this area cluster together based on similar tuning for shape and texture, but these clusters are mainly found in specific layers rather than structured like vertical columns.
- The study suggests that the organization of area V4 is coarse and focuses on broader shape features rather than fine details, possibly due to the wide variety of visual inputs that V4 neurons receive.

Article Synopsis
- Sleep dysfunction is common in Huntington's disease (HD) and can worsen symptoms and quality of life while potentially speeding up the disease's progression.
- Current treatments for HD do not address sleep issues or the effects of medications on sleep.
- The review evaluates existing research and presents a framework for understanding how different medications affect sleep, along with highlighting new therapies for sleep dysfunction in HD.
