To Enhance Sensory Activities, The Brain Combines Touch and Sound.
Summary: The inferior colliculus, a midbrain region known for sound processing, also plays a role in touch sensation by integrating tactile and auditory signals. Pacinian corpuscles, highly sensitive skin mechanoreceptors, relay high-frequency vibrations to this brain area, amplifying sensory experiences. This mechanism explains phenomena like feeling music vibrations during a
Irritation and Condition Are Associated with Canadian Clocks.
Summary: New research reveals how the body’s circadian clock regulates macrophage activity, influencing immune system inflammation throughout the day. Activation of the NLRP3 inflammasome, a key component in the immune response, peaks during the morning when macrophages are most efficient. This daily rhythm is driven by mitochondrial activity, explaining why
Visible errors are linked to anxious beliefs in a study.
Summary: A new study suggests complex beliefs like paranoia may have roots in visual misperception. Participants prone to paranoia or teleological thinking were more likely to wrongly identify one moving dot as chasing another in a visual task.Paranoia and teleological thinking differ in their errors, suggesting distinct cognitive patterns. The
A room investigation reveals people brain cells’ faster growth has been detected.
Summary: Scientists sent stem-cell-derived brain organoids to the International Space Station (ISS) to study the effects of microgravity on brain development. After a month in orbit, the organoids remained healthy but displayed accelerated maturation and reduced replication compared to Earth-grown controls.Gene expression analysis revealed higher levels of genes linked to
Targeted or Broadcast? How the Brain Processes Visual Data
Summary: Researchers have uncovered how visual information is processed across the brain’s complex and flexible networks.One study showed visual signals are selectively targeted or broadly broadcast, challenging the idea of a simple, linear flow of visual input. A second study revealed that the thalamus adapts visual processing based on behavioral
Baby Babble synchronizes breaths with conversation development
Summary: Infants’ heart rate rhythms are closely linked to their early vocalizations, including coos, babbles, and emerging words. Researchers found that babies were most likely to produce sounds when their heart rate reached a peak or trough, with speech-like sounds occurring during heart rate deceleration.This connection highlights how heart rate
