COVID-19 linked to rare form of encephalitis

A patient who tested positive for COVID-19 developed acute necrotizing encephalitis (ANE) as a result of the coronavirus infection. An MRI scan revealed the patient had lesions in the thalamus and temporal lobes, areas of the brain implicated in consciousness, sensation, and memory function. Researchers advise doctors to look out for COVID-19 patients who present with altered levels of consciousness, as this may be symptomatic of ANE.

A delicate dance of dynamic changes in the conscious brain

The brain quickly transitions from one network to another in regular patterns. The transition trajectories constitute a temporal circuit where the conscious brain cycles through a structured pattern of states over time.

Researchers stimulate areas vital to consciousness in monkeys’ brains, and it wakes them up

Stimulating the central lateral thalamus in monkeys under anesthesia was enough to wake the animals and elicit normal waking behaviors.

Ayahuasca DMT compound changes brainwaves to vivid ‘waking-dream’ state

DMT alters electrical activity in the brain. The compound significantly decreases alpha wave activity, the dominant rhythm associated with wakefulness, and increases theta waves, associated with dreaming. Overall brain activity becomes more chaotic and less predictable. The findings advance the understanding of the neurobiological underpinnings of immersive states of consciousness.

Finding the root of consciousness: Is this brain cell your ‘mind’s eye’?

Researchers believe they have identified specific neurons that are responsible for conscious awareness. Previous studies have implicated both thalamocortical circuits and cortico-cortico circuits in consciousness. The new study reports these networks intersect via L5p neurons. Directly activating L5p neurons made mice react to weaker sensory stimuli. The researchers say if consciousness requires L5p neurons, all brain activity without them must be unconscious.
