The paper is concerned with a study of patients with attack-like progressive schizophrenia--children from 7-9 years. The clinical picture was characterized by affective--delusional attacks of a paraphrenic structure. The interpretative delusion of persecution was in combination with delusional structures of the type of confabulations with false reminiscence.

Structured internal representations ('cognitive maps') shape cognition, from imagining the future and counterfactual past, to transferring knowledge to new settings. Our understanding of how such representations are formed and maintained in biological and artificial neural networks has grown enormously. The cognitive mapping hypothesis of schizophrenia extends this enquiry to psychiatry, proposing that diverse symptoms - from delusions to conceptual disorganization - stem from abnormalities in how the brain forms structured representations.

Sleepwalking and related parasomnias are thought to result from incomplete awakenings out of non-rapid eye movement (non-REM) sleep. Non-REM parasomnia behaviours have been described as unconscious and automatic, or related to vivid, dream-like conscious experiences. Similarly, some observations have suggested that patients are unresponsive during episodes, while others that they can interact with their surroundings.

Gamma oscillations nested in a theta rhythm are observed in the hippocampus, where are assumed to play a role in sequential episodic memory, i.e., memorization and retrieval of events that unfold in time.

According to classical phenomenology, phenomenal experience is composed of perceptions (related to environmental stimuli) and imagery/ideas (unrelated to environmental stimuli). Intensity/vividness is supposed to represent the key phenomenal difference between perceptions and ideas, higher in perceptions than ideas, and thus the core subjective criterion to distinguish reality from imagination. At a neural level, phenomenal experience is related to brain activity in the sensory areas, driven by receptor stimulation (underlying perception) or associative areas (underlying imagery/ideas).

Article Synopsis
- Hypnosis has a rich 250-year history, evolving from early ideas like animal magnetism to play a role in psychotherapy, psychosomatics, and medicine, emphasizing imagination's importance in treatment.
- Concepts of the mind-body problem were explored in early romantic ideas of hypnosis, influencing modern understandings of unconscious processes and linking hypnosis to cognitive behavioral therapy techniques.
- Ongoing debates in social psychology question whether hypnosis is a unique state of consciousness or a normal interaction, with research showing that even moderately hypnotizable individuals can benefit and that factors like motivation and rapport are crucial for effective hypnotherapy.
