Today we hosted a gathering outside the University of Dundee, to coincide with the visit of Ben Macpherson MSP, Minister for Higher and Further Education.

Ahead of his meeting with unions and students, the Minister took some time to come and speak to us.

Join UCU Why join UCU? Over 120,000 of your colleagues have chosen to belong to UCU - the largest union and most effective voice for people like you working in post-school education.

Join the University and Colleges Union branch at the University of Dundee today.

Our strike action and lobbying was a major factor in securing additional funding for the University.

We consistently protect our members and ask for redundancies to be ruled out.

The current situation at the University of Dundee is that we are not getting our annual pay increase and that promotion processes are paused.

At the same time the uni is refusing to rule out compulsory redundancies, it is advertising over 20 new senior management jobs for academic staff.

Today, we are out on strike again to save our jobs and tap the sign that Scottish (and in extension UK) Higher Education is not doing well, largely due to financial mismanagemement. This is all currently put on display by our Union reps in the Scottish parliament ⬇️ @ducuuo.bsky.social

Narration:
Hallucinations are complex phenomena occurring involuntarily to individuals with a mental disorder. They are often feared and unwanted. 

Narration:
 But what if they can be controlled? What if we could intentionally induce them in a secure way, so we can better understand them?

Narration:
In order for an experimentally induced hallucination to form, the mind must be presented with something specific that is visually very different from what it is accustomed to seeing.

Narration:
Sensory deprivation: The lack of stimuli (specifically visual). Participants engaging in this method of hallucination induction can be completely blindfolded or left in a pitch black environment. Either way, their mind must not be exposed to light.

Narration:
Ganzfeld: A uniformly colored, luminary visual field (e.g. a clear blue sky or a singular color on a screen). Exposure to ganzfeld can induce slight visual hallucinations. 
(Figure laying on the grass, facing a clear blue sky.)

Narration:
Sensory deprivation can be an unreliable method for the intention of experiencing induced hallucinations. Visuals aren’t always guaranteed, and it can take hours or even days for imagery to start showing up. 
(Figure sitting on the ground, blindfolded. Cobwebs are on the figure, signifying a long time has passed. A little spider is next to the figure.)

Narration:
Ganzfeld is also not very reliable. Though most individuals experience visuals, they are not very complex. Most experience colors and simple geometric patterns after a while.
(Side view of a head, a cloud forming from their head that contains simple geometric shapes.)

Narration:
But is there a way to induce complex and vivid hallucinations almost immediately and comfortably? There sure is!
(Two figures, shoulders up, next to each other. Exclamation marks next to one, and a question mark next to the other. They are both looking at the text bubble.)

I use EEG/MEG. When I meet like-minded researchers at conferences, the discussion always circles back to one thing: admitting that results may be confounded by leakage (also known as remaining field spread—RFS). In our new preprint, we quantify RFS in parcellated data using cross-talk function—CTF.🧵

Out now in Communications Biology 🧠 🫀We show that cardiac oscillations associated with vagal tone influence the strength of the heartbeat as sensed at brain level. We hypothesize that the heart may send information to the brain, encoded by the heartbeat strength doi.org/10.1038/s420...

‘Angry and exhausted’ Dundee University staff rally against jobs cut to save university Campus unions organised the event where there was palpable anger at the current and former leadership of Dundee University.

We resolve to continue opposing compulsory lay-offs and a radical reshaping of the institution.

If we fight together we win!
