While NASA gets the glory for exploration of the vast unknown of space, Bionaut Labs Ltd. hopes to reap similar fame by transforming travel through the brain with Bionauts, microrobots designed to deliver therapeutic payloads across the blood-brain barrier. To help achieve that mission, the company raised $43.2 million in a series B financing round led by Khosla Ventures.

Mdoloris Medical Systems SAS and Pprs SAS reported a joint venture to launch ANI Guardian, a connected medical device that continuously and non-invasively tracks pain levels and well-being in a range of non-verbal or cognitively impaired people.

Stimulating the brain via implanted electrodes is used to treat both movement disorders such as Parkinson’s disease, and some psychiatric conditions such as obsessive compulsive disorder. But researchers are also working on ways to make such implanted electrodes listen instead of talk – and translate neuronal signals for people that have lost the ability speak, or the ability to move.

One way psychiatric disorders differ from neurological disorders is by the absence of anatomically defined neuropathology. “Alzheimer's disease, Parkinson's disease or stroke have a very clear picture of what cells are changing and how they're changing. The specific changes are very clear under a microscope, but in psychiatric diseases one hasn't been able to see that,” Daniel Geschwind told BioWorld.

By pairing the expression of an inhibitory ion channel with an activity-dependent promoter, researchers have developed the first on-demand gene therapy that specifically silenced hyperactive cells and prevented epileptic seizures.

Ariemedi Medical Technology (Beijing) Co. Ltd. has completed a series A+ round to further develop its medical devices for minimally invasive surgeries. The round was co-invested by Haining Hairui Investment Management Co. Ltd. and Haier Capital.

It was a good week for companies focused on minimally invasive brain surgery. Monteris Medical Corp. received $35 million in a series D equity financing and a $38 million debt facility to support market adoption and clinical research on its Neuroblate system, a laser ablation system that provides a minimally invasive option for brain surgery. Nico Corp. also raised additional funds, with a $12.5 million oversubscribed round for its devices, which do not require cutting through the brain but instead use the natural folds of the brain to reach abnormalities.

Circuit dysfunction is clearly recognized as a driver of neuropsychiatric disease, and some neurodegenerative diseases such as Parkinson’s disease. And at the European Committee for Treatment and Research in Multiple Sclerosis (ECTRIMS) 2022 Congress, researchers made an argument that the same is true in multiple sclerosis (MS). Such a lens could explain the radiological-clinical paradox between the amount of structural damage and clinical severity.
