Multimodal MRI Reveals Brainstem Connections That Sustain Wakefulness in Human Consciousness

Major Breakthrough in Brain Science: Multimodal MRI Reveals Brainstem Connectivity Maintaining Human Consciousness and Wakefulness Background Introduction Consciousness comprises two fundamental components: wakefulness and awareness. Despite significant progress in understanding the cortical networks related to consciousness over the past two decad...

Nociceptor Spontaneous Activity is Responsible for Fragmenting Non-Rapid Eye Movement Sleep in Mouse Models of Neuropathic Pain

Research Background and Motivation Neuropathic pain is a complex and common clinical issue, accompanied by persistent spontaneous pain. Patients often report symptoms such as spontaneous pain, electric shock sensations, and burning pain. The physiological mechanisms behind this type of pain are complex, and reliable research models or biomarkers ar...

Neuronal population activity in the olivocerebellum encodes the frequency of essential tremor in mice and patients

Encoding of Cerebellar-Olivary Neuronal Ensemble Activity for Tremor Frequency in Mice and Patients with Essential Tremor Research Background Essential Tremor (ET) is a common movement disorder characterized primarily by action tremor, affecting about 20% of the elderly population. The frequency and intensity of tremor are core features of ET. Howe...
