Cryo-EM Reveals Structural Differences in Fetal and Adult Muscle Receptors

The connections between the nervous system and muscles develop differently across the kingdom of life. It takes newborn humans roughly a year to develop the proper muscular systems that support the ability to walk, while cows can walk mere minutes after birth and run not long after.

How Seba's Short-Tailed Bats Navigate Their Acoustic World

The world of bats is full of sounds. They utilize vocalizations for both navigation and communication with their conspecifics. For the latter, they produce ultrasonic noises that reverberate and allow them to form a mental "image" of their environment

The Intricate Network of Stick Insects’ Leg Muscles

Researchers at the University of Cologne have discovered new details on the process underlying the stick insect’s leg muscles’ rhythmic activation of nerve cells, or neurons. Unlike the neurons in the other leg muscles, the researchers demonstrated that the neurons in the leg depressor muscle are activated rhythmically.

Breathing Patterns Linked to Memory Consolidation During Sleep

How are memories consolidated during sleep? In 2021, researchers led by Dr. Thomas Schreiner, leader of the Emmy Noether junior research group at LMU's Department of Psychology, had already shown there was a direct relationship between the emergence of certain sleep-related brain activity patterns and the reactivation of memory contents during sleep.
