This process ensures precise blood flow delivery to active neurons, crucial for brain health and cognitive function. ]]> 106917 https://neurosciencenews.com/heart-brain-nervous-system-28177/ Wed, 04 Dec 2024 20:29:14 +0000 https://neurosciencenews.com/?p=106732 New research reveals the heart has its own complex nervous system, or "mini-brain," capable of regulating the heartbeat independently of the brain. Conducted on zebrafish, the study identified specialized neurons within the heart, including some with pacemaker properties, challenging traditional views of heartbeat control.]]> 106732 https://neurosciencenews.com/pain-expectation-neuroscience-27660/ Mon, 23 Sep 2024 18:17:51 +0000 https://neurosciencenews.com/?p=104593 New research reveals how the brain combines pain expectations with actual pain intensity, offering insights into the brain's pain integration process. Using fMRI, scientists found that while all brain networks store pain information, only higher-level networks integrate pain expectations and stimuli into a cohesive experience.]]> 104593 https://neurosciencenews.com/electrical-impulses-brain-cancer-27615/ Thu, 05 Sep 2024 13:56:43 +0000 https://neurosciencenews.com/?p=104392 Researchers have discovered a new type of brain cell that fires electric impulses, challenging the long-held belief that only neurons can do so. These hybrid cells, part neuron and part glia, were found in both glioma tumors and healthy human brains. ]]> 104392 https://neurosciencenews.com/consciousness-death-brain-activity-27501/ Tue, 30 Jul 2024 18:50:53 +0000 https://neurosciencenews.com/?p=103924 A recent study found increased brain activity in two dying patients, but it does not indicate consciousness. The research revealed gamma wave bursts in comatose patients with epilepsy, but no evidence these were tied to conscious experiences.]]> 103924 https://neurosciencenews.com/brain-micro-sleep-26448/ Tue, 16 Jul 2024 20:42:17 +0000 https://neurosciencenews.com/?p=103698 New research shows sleep can be detected by brain activity patterns just milliseconds long. This study found small brain regions can momentarily "flicker" awake or asleep, challenging traditional views on sleep and wake states.]]> 103698 https://neurosciencenews.com/excitation-inhibition-cognition-development-26320/ Thu, 13 Jun 2024 21:37:51 +0000 https://neurosciencenews.com/?p=103139 A new study reveals that a balanced ratio of neural excitation (E) and inhibition (I) is crucial for brain development and cognitive performance. Researchers found that lower E/I ratios in children correlate with better memory and intelligence. This balance is vital for preventing brain disorders and was measured using a novel AI and MRI technique. The findings could inform personalized treatments for mental health conditions.]]> 103139 https://neurosciencenews.com/electrophysiology-neuron-response-26238/ Tue, 04 Jun 2024 19:46:21 +0000 https://neurosciencenews.com/?p=102796 Researchers discovered that different neuron types exhibit distinct patterns of response to electrical stimulation (ES). Using precise tissue sampling, they found excitatory neurons sync with both slow and fast ES, while inhibitory neurons respond mainly to fast frequencies. ]]> 102796 https://neurosciencenews.com/hippocampus-projectome-25550/ Thu, 01 Feb 2024 20:51:34 +0000 https://neurosciencenews.com/?p=99816 Researchers unveiled the most extensive single-neuron projectome database to date, featuring over 10,000 mouse hippocampal neurons.
