Dissociation between area TE and rhinal cortex in accuracy vs. speed of visual categorization in rhesus monkeys.
Front Behav Neurosci

Laboratory of Neuropsychology, National Institute of Mental Health, National Institutes of Health, Bethesda, MD, United States.
In real-world vision, objects may appear for a short period, such as in conjunction with visual search. Presumably, this puts a premium on rapid categorization. We designed a visual categorization task cued by briefly presented images to study how visual categorization is processed in an ethologically relevant context.

Article Synopsis
- Scientists studied how insects like moths and fruit flies use smells (pheromones) to find their way and communicate.
- They created a special device that sends short bursts of pheromones to see how the insect's sensory cells react.
- Moths can recognize when the smell stops, but fruit flies can't do this well because they only need to communicate over short distances.
Comparing cranial suture interdigitation in humans and non-human primates: unearthing links to osteopathic cranial concept.
J Osteopath Med
September 2024
Western University of Health Sciences, COMP Northwest, Lebanon, OR, USA.
Context: Since William Garner Sutherland's inception of osteopathic cranial manipulative medicine (OCMM), osteopathic physicians have practiced with the knowledge that cranial sutures exhibit motion. We hypothesize that the complexity of suture interdigitation in humans may provide clues to elucidate the concept of OCMM.
Objectives: We compared the interdigitation of sagittal, coronal (left and right), and lambdoid (left and right) sutures in computed tomography (CT) scans of humans and five nonhuman primate species (, , , , and ).
Noises on-How the Brain Deals with Acoustic Noise.
Biology (Basel)
July 2024
Neuroscience Research Center, Charité-Universitätsmedizin Berlin, 10117 Berlin, Germany.
What is noise? When does a sound form part of the acoustic background and when might it come to our attention as part of the foreground? Our brain seems to filter out irrelevant sounds in a seemingly effortless process, but how this is achieved remains opaque and, to date, unparalleled by any algorithm. In this review, we discuss how noise can be both background and foreground, depending on what a listener/brain is trying to achieve. We do so by addressing questions concerning the brain's potential bias to interpret certain sounds as part of the background, the extent to which the interpretation of sounds depends on the context in which they are heard, as well as their ethological relevance, task-dependence, and a listener's overall mental state.

Amongst fishes, zebrafish (Danio rerio) has gained popularity as a model system over most other species and while their value as a model is well documented, their usefulness is limited in certain fields of research such as behavior. By embracing other, less conventional experimental organisms, opportunities arise to gain broader insights into evolution and development, as well as studying behavioral aspects not available in current popular model systems. The anabantoid paradise fish (Macropodus opercularis), an "air-breather" species has a highly complex behavioral repertoire and has been the subject of many ethological investigations but lacks genomic resources.
