Neuropsychedelia: The Revival of Hallucinogen Research Since the Decade of the Brain
"Neuropsychedelia examines the revival of psychedelic science since the "Decade of the Brain." After the breakdown of this previously prospering area of psychopharmacology, and in the wake of clashes between counterculture and establishment in the late 1960s, a new generation of hallucinogen researchers used the hype around the neurosciences in the 1990s to bring psychedelics back into the mainstream of science and society. This book is based on anthropological fieldwork and philosophical reflections on life and work in two laboratories that have played key roles in this development: a human lab in Switzerland and an animal lab in California. It sheds light on the central transnational axis of the resurgence connecting American psychedelic culture with the home country of LSD.

In the borderland of science and religion, Neuropsychedelia explores the tensions between the use of hallucinogens to model psychoses and to evoke spiritual experiences in laboratory settings. Its protagonists, including the anthropologist himself, struggle to find a place for the mystical under conditions of late-modern materialism."

[MY NOTE: Hamilton Morris was more enthusiastic about this book than any of the 3 he recommended on Tim's podcast. Looks really good.]

Your Brain Doesn't Contain Memories. It Is Memories | WIRED
That means your brain is literally made of memories, and memories constantly remake your brain. This framework for memory dates back decades. And a sprawling new review published today in Neuron adds an even finer point: Memory exists because your brain’s molecules, cells, and synapses can tell time.

Brain-wide Organization of Neuronal Activity and Convergent Sensorimotor Transformations in Larval Zebrafish - ScienceDirect
Simultaneous recordings of large populations of neurons in behaving animals allow detailed observation of high-dimensional, complex brain activity. However, experimental approaches often focus on singular behavioral paradigms or brain areas. Here, we recorded whole-brain neuronal activity of larval zebrafish presented with a battery of visual stimuli while recording fictive motor output. We identified neurons tuned to each stimulus type and motor output and discovered groups of neurons in the anterior hindbrain that respond to different stimuli eliciting similar behavioral responses. These convergent sensorimotor representations were only weakly correlated to instantaneous motor activity, suggesting that they critically inform, but do not directly generate, behavioral choices. To catalog brain-wide activity beyond explicit sensorimotor processing, we developed an unsupervised clustering technique that organizes neurons into functional groups. These analyses enabled a broad overview of the functional organization of the brain and revealed numerous brain nuclei whose neurons exhibit concerted activity patterns.
