New synaptic formation in adolescence challenges conventional views of brain development

Researchers from Kyushu University found that the brain forms new, high-density clusters of synapses on specific segments of dendrites during adolescence, challenging the 'adolescent synaptic pruning' hypothesis. This discovery may offer new hope for understanding the biological basis of schizophrenia and other neurodevelopmental condi...

40-Hz auditory stimulation shows long-term efficacy in aged monkeys, offering potential for non-invasive Alzheimer's therapy

Researchers demonstrated that 40-Hz auditory stimulation significantly elevates beta-amyloid levels in the cerebrospinal fluid of aged rhesus monkeys, with effects persisting for over five weeks. The study provides evidence supporting 40-Hz stimulation as a non-invasive therapy for Alzheimer's disease.

To flexibly organize thought, the brain makes use of space

Researchers tested Spatial Computing theory by examining neural activity and brain wave patterns in animals performing working memory and categorization tasks. The findings support the theory's predictions, including that alpha/beta waves represent task controls and rules, while spiking activity carries sensory information.

MIT researchers identified three cognitive skills we use to infer what someone really means

Researchers at MIT have identified three clusters of pragmatic skills that are based on the same kinds of inferences and may have similar underlying neural processes. These skills include interpreting social conventions, understanding physical world knowledge, and distinguishing between tones to convey emphasis or emotion.

Prefrontal cortex reaches back into the brain to shape how other regions function

Researchers found that the prefrontal cortex sends customized signals to visual and motor regions, influencing their activity based on arousal levels and movement. The study reveals distinct roles of prefrontal subregions in shaping visual processing, with one region enhancing stimuli detection and another dampening irrelevant stimuli.
