Diane Hennacy

Diane Hennacy, Johns Hopkins–trained neuropsychiatrist and former Harvard faculty who studies autism, savant syndrome and ESP. She recounts how clinical encounters led her into parapsychology. Conversations cover hippocampus and memory, autistic savants and high-accuracy telepathy tests, neuronal and glial mechanisms, ketosis and brain metabolism, and experimental methods for proving or disproving alleged psychic phenomena.

INSIGHT

Right-Hemisphere Traits Support Receptivity

Diane argues autistic brains are more right-hemisphere or hybrid, matching dreaming and creative states linked to receptivity.
She suggests modern left-hemisphere schooling suppresses perceptual modes that enable ESP-like access.

ADVICE

Form Multidisciplinary Teams For New Tests

Collaborate across physics and neuroscience to design experiments on microtubules and consciousness.
Diane recommends forming multidisciplinary teams to brainstorm feasible tests of non-neuronal brain systems.

ADVICE

Explore Noninvasive Light And Sound Therapies

Consider low-intensity ultrasound and nasal infrared as noninvasive neuromodulation options for cognitive conditions.
Diane notes clinical use of nasal red/infrared devices and targeted ultrasound show early promise for Alzheimer's and brain repair.

España

A Brief History of Spain

Giles Tremlett

In 'España', Giles Tremlett traverses the rich and varied history of Spain, from prehistoric times to today. The book covers Spain's connections to ancient empires such as the Phoenicians, Romans, Carthaginians, and Byzantines, as well as its colonization of the Americas. Tremlett argues that Spain's defining trait is its lack of a homogenous identity, shaped by generations of changing peoples worshipping Christian, Jewish, and Muslim gods. The book is filled with color illustrations and provides a brisk and informative account of Spain's multifaceted history.

Diane Hennacy, M.D. is a Johns Hopkins-trained neuropsychiatrist and neuroscientist, former Harvard faculty member, and an award-winning author and clinician. She began studying autism in 1987, when she spent six months with Sir Michael Rutter at the Institute for Psychiatry in London. Her decades long research focused on investigating reports of telepathy and precognition in autistic children was the inspiration for The Telepathy Tapes.
