Documented anomalies of the brain — real, recorded neurological conditions, and the myths around them. 19 case files in the archive.
The rare neurological disorder in which brain injury alters speech so it sounds foreign. The real mechanism, the famous 1941 Norwegian case, and why waking up speaking a new language is a myth.
The documented sensation, movement, and pain amputees feel in a limb that is no longer there. Silas Weir Mitchell 1871 description, the cortical-remapping explanation, and Ramachandran mirror-box therapy.
The documented, measurable physiological responses to expectation alone. The endogenous-opioid and dopamine mechanisms, open-label placebo studies, and why these are real biology, not imagination.
Extraordinary islands of skill (memory, calendar calculation, music, art, math) alongside disability, and the rare acquired savant who gains such abilities after brain injury. Kim Peek, Treffert research, and hidden brain capacity.
The documented but unexplained return of mental clarity in some dying patients with advanced dementia or severe brain disease. The case reports, the 2009 framing by Michael Nahm, and why current neuroscience cannot account for it.
The documented neurological condition in which one sense automatically triggers another: seeing colors in letters, tasting words, hearing shapes. The grapheme-color type, the cross-activation explanation, and how it is tested.
The Capgras delusion (my family have been replaced by impostors) and the Cotard delusion (I am dead). Two documented neuropsychiatric conditions, the disconnection between recognition and emotion, and what they reveal about the self.
The documented condition in which people blinded by damage to the visual cortex can still respond to visual stimuli they cannot consciously see. Weiskrantz patient DB, the second visual pathway, and what it reveals about consciousness.
The documented inability to recognize faces despite intact vision and intelligence. The fusiform face area, the acquired and developmental forms, and how people who cannot recognize their own families cope.
The documented absence of a minds eye, the inability to voluntarily form mental images. Galton 1880 foreshadowing, Adam Zeman 2015 naming, the spectrum to hyperphantasia, and what it reveals about imagination and memory.
The documented state of being awake but unable to move, often with a sense of a presence in the room. The REM-atonia mechanism, the cross-cultural folklore (the Old Hag, kanashibari), and its link to alien abduction and night-demon experiences.
The documented condition in which a person hand acts purposefully but involuntarily, feeling as if it has a will of its own. The split-brain and frontal/callosal lesion causes, and what it reveals about will and agency.
The documented, consistent experiences reported by people close to death: the tunnel, the light, out-of-body sensations, life review. The prospective studies, the proposed neurobiological mechanisms, and the survivalist-versus-naturalist debate.
The documented audiovisual illusion in which watching a mouth shape one sound while hearing another makes you perceive a third. The 1976 discovery, the multisensory-integration mechanism, and why it persists even when you know.
The documented condition of distorted perception of size, shape, body image, and time. The migraine and Epstein-Barr links, the 1955 naming, and why it is usually benign and transient.
The documented, harmless sleep phenomenon in which a person perceives a sudden loud noise, like a bang or explosion, while falling asleep or waking. The sleep-transition mechanism, the lack of pain, and why it is benign.
Highly Superior Autobiographical Memory, the documented ability to recall an extraordinary amount of ones personal past in vivid detail. The first case AJ, the McGaugh research, the specific nature of the gift, and what it reveals about memory.
The phenomenon of large numbers of people sharing the same false memory. The classic examples, the memory-science explanation (reconstruction, schema, social contagion), and why the parallel universe interpretation is unsupported.
The documented sensation of perceiving the world from outside ones physical body. Olaf Blanke temporoparietal-junction induction, the multisensory-integration mechanism, the VR body illusions, and the survivalist debate.
