This real case explains everything:

CT scan of the brain of a 44-year-old civil servant who has lost more than 90% of his brain tissue due to hydrocephalus, but lives almost a normal life with two children, having verbal IQ 84 and performance IQ 70 (Lancet. 2007;370(9583):262). The scan picture supports the view that for conscious activities, minimal neural structures required are the upper layers of the cerebral cortex and the brainstem.

90% of his brain is gone.​

This paper may have some relevance as well.

Evidence of conditioned behavior in amoebae​

https://pmc.ncbi.nlm.nih.gov/articles/PMC6695432/

"Here we describe a motility pattern consistent with associative conditioned behavior in the microorganism Amoeba proteus. We use a controlled direct-current electric field as the conditioned stimulus, and a specific chemotactic peptide as the unconditioned stimulus. The amoebae are capable of linking two independent past events, generating persistent locomotion movements that can prevail for 44 min on average. We confirm a similar behavior in a related species, Metamoeba leningradensis. Thus, our results indicate that unicellular organisms can modify their behavior during migration by associative conditioning."

However in our study, the stimuli are apostilled documents in duplicate.
 
It's commendable how OCT contributes to science.

I also suggest this paper about bank employees: https://www.nature.com/articles/s41598-021-82021-w.pdf

“monkeys are moved from their home cage to an experimental room daily, where they sit in a primate chair and interact with electronic devices”

“even with challenging tasks, monkeys can complete a large number of trials at a high performance level”
