Bayi baru lahir menunjukkan kemampuan saraf bawaan untuk memahami angka

Sebuah studi baru menemukan bahwa bayi memiliki mekanisme otak untuk kemampuan dasar memahami angka dalam hitungan hari setelah lahir. Para peneliti menggunakan rekaman EEG untuk menunjukkan bagaimana bayi baru lahir membedakan jumlah yang berbeda. Temuan ini memberikan bukti saraf pertama untuk kemampuan bawaan ini.

Para peneliti di University of Trento di Italia memasangkan topi EEG pada 21 bayi baru lahir berusia antara 0 hingga 3 hari untuk memantau aktivitas otak. Bayi-bayi tersebut mendengarkan rekaman suku kata berulang dalam kelompok empat atau 12 sambil melihat rangkaian titik yang cocok atau tidak cocok.

Aktivitas listrik menurun di area parietotemporal ketika jumlah titik selaras dengan suku kata. Aktivitas meningkat dengan jumlah yang tidak cocok, yang menunjukkan penekanan pengulangan serupa dengan pola yang terlihat pada orang dewasa.

Marco Buiatti, yang memimpin studi tersebut, mencatat bahwa kemampuan ini menawarkan keuntungan evolusioner untuk tugas bertahan hidup seperti membedakan predator atau sumber makanan. Karya tersebut diunggah di bioRxiv pada Mei 2026.

Study finds brain-wide activity in zebrafish predicts social approach seconds before movement

Researchers at the Hebrew University of Jerusalem report that a coordinated pattern of brain activity emerges several seconds before zebrafish swim toward another fish, and that the strength of the signal is linked to individual differences in sociability.

Study links birth epigenetic markers and early gut bacteria with autism- and ADHD-related traits by age 3

A study involving infants in Hong Kong found that DNA methylation patterns measured at birth were associated with how the gut microbiome developed during the first year of life, and that certain combinations were linked to autism- and ADHD-related behavioral signs at 36 months.

Researchers propose lineage model for brain development

Kamis, 25 Juni 2026 Dilaporkan oleh AI

A new theory from scientists at Cold Spring Harbor Laboratory suggests that brain cells use their cellular family tree to organize into a complex organ. The model explains how a single starting cell can form a brain with roughly 170 billion precisely positioned neurons.

Brainstem neurons identified as key to blocking distractions

Researchers at Johns Hopkins University have discovered a group of neurons in an ancient brain region that helps filter distractions and maintain focus. Experiments in mice showed that temporarily disabling these cells led to increased distractibility similar to symptoms seen in ADHD.

Study links speech learning and memory to auditory and somatosensory cortex, not motor cortex

A study by researchers at McGill University and Yale School of Medicine suggests that learning—and later retaining—new speech patterns depends more on brain areas that process sound and bodily sensation than on the motor cortex regions that control speech movements. The work was published in the Proceedings of the National Academy of Sciences.
