Animals capable of complex behaviors tend to have more distinct brain areas than simpler organisms, and artificial networks that perform many tasks tend to self-organize into modules (1-3). This suggests that different brain areas serve distinct functions supporting complex behavior. However, a common observation is that essentially anything that an animal senses, knows, or does can be decoded from neural activity in any brain area (4-6).

The size of a neuron's receptive field increases along the visual hierarchy. Neurons in higher-order visual areas integrate information through a canonical computation called normalization, where neurons respond sublinearly to multiple stimuli in the receptive field. Neurons in the visual cortex exhibit highly heterogeneous degrees of normalization.

Article Synopsis
  • Obesity is linked to heart failure with preserved ejection fraction (HFpEF), characterized by changes in heart structure and increased epicardial adipose tissue (EAT), which can lead to negative health outcomes.
  • The SUMMIT trial's CMR substudy aimed to assess how tirzepatide influenced cardiac structure and function in patients with obesity-related HFpEF, focusing on its potential to lower left ventricular (LV) mass and EAT.
  • Results showed that tirzepatide treatment significantly reduced LV mass by 11 g and paracardiac adipose tissue by 45 ml compared to placebo, with changes in LV mass correlated to body weight and other cardiac measures.

Dysregulated proteostasis in cardiomyocytes is an important pathological event in cardiomyopathy, which can be repaired by inhibiting mechanistic target of rapamycin (mTOR) for cardioprotective effects. Here, we aimed to uncover additional pathological events and therapeutic target genes via leveraging zebrafish genetics. We first assessed transcription factor EB ( ), a candidate gene that encodes a direct downstream phosphorylation target of mTOR signaling.

Article Synopsis
  • Galcanezumab is a medicine used to help prevent migraines in adults, especially women who might get pregnant, but we don't know much about its safety during pregnancy yet.
  • There's a study tracking pregnancies where women took galcanezumab, using health insurance data from September 2018 to June 2026, and they need 430 such cases to learn more about any potential risks.
  • So far, they've found 207 pregnancies linked to the medicine but need many more to complete the study, which is an obstacle in getting safer pregnancy information out to doctors and patients.
