My post on the brainfacts blog, “Let’s stop using the term “Hard Wired“. Intended to get people to think more carefully and avoid sloppy metaphors.
I’ve been working on an idea for several months: that exerting effort, force, has an subjective feeling, a quale, which lays behind a person’s intuitive idea of physics and causality.
Love is both physical and psychological. It is both biological and a conscious emotion. The study of love, as with much of Neuroscience, crosses boundaries.
Here’s My blog post on BrainFacts for valentine’s day. It’s largely an introduction to Lucy Brown and Helen Fischer’s website, AnatomyOfLove.com plus Q-and-A with Lucy. (Hit “continue reading” for Billie Hiliday’s rendition). Continue reading
Judicial Punishment in a Neuroscientific World
We’ve witnessed a steady stream of books and articles about the relationship between a Neuroscience and judicial philosophy. Although I am far from an expert, I’ll describe what I believe are the rationales for legal punishment. This will be followed by personal reflects the legal system, Neuroscience and Psychology1.

“You are standing by your paper-tube in Englewood reading the headlines. Your neighbor comes out to get his paper. You look at him sympathetically. You know he has been having severe chest pains and is facing coronary bypass surgery. But he is not acting like a cardiac patient this morning. Over he jogs in his sweat pants, all smiles. He has triple good news. His chest ailment turned out to be a hiatal hernia, not serious. He’s got a promotion and is moving to Greenwich, where he can keep his boat in the water rather than on a trailer. “Great, Charlie! I’m really happy for you.” Are you happy for him?
(a) Yes. Unrelievedly good news. Surely it is good news all around that Charlie is alive and well and not dead or invalided. Surely, too, it is good for him and not bad for you if he also moves up in the world, buys a house in Greenwich where he can keep a 25-foot sloop moored in the Sound rather than a 12-foot Mayflower on a trailer in the garage in Englewood.
(b) Putatively good news but— but what? But the trouble is, it is good news for Charlie, but you don’t feel so good.
— Walker Percy’s (1983) “Lost in the Cosmos: The last Self-Help Book” 
In 1981 I was an eager post-doctoral fellow, learning to record place cell’s in Jim Ranck’s lab and beginning to understand John O’Keefe and Lynn Nadel’s “Cognitive Map” theory of the hippocampus. One afternoon, while I had a rat in the maze and watched traces of action potentials sweep by on the oscilloscope, Jim Ranck looked over my should and said …
“This is terrific! Place cells are the gateway to understanding how the brain produces cognition.”1
This was both inspirational and opaque. Continue reading
The WordPress.com stats helper monkeys prepared a 2013 annual report for this blog.
Here’s an excerpt:
The concert hall at the Sydney Opera House holds 2,700 people. This blog was viewed about 17,000 times in 2013. If it were a concert at Sydney Opera House, it would take about 6 sold-out performances for that many people to see it.
“I still believe in Santa Claus. I think I’ll believe in Santa one more year.”
There are several amazing things in this statement. Continue reading
Poster: Hippocampal remapping involves competition between entorhinal inputs – SfN Tuesday Morning: 576.20
Authors: J. Dickinson, A. Weible, D. Rowland, C. Kentros
Place cells are recorded in CA1 and CA3 fields of the hippocampus. The major afferents to the hippocampus come from entorhinal cortex. When grid cells were first described in recordings from layer 2 of medial entorhinal cortex it was largely assumed that place cell patterns arose from through a summation of grid cell inputs.

Poster: Organization of the neuronal assemblies in the anterior thalamus coding for head direction 326.14 (Mon Morning)
Authors: A. Peyrache, M. Lacorix, P. Petersen, G. Buzsaki; NYU
Head-direction cells are neurons that fire when ever a rat’s head is pointed in a particular direction. Discovered by Jim Ranck and first reported at SfN 29 years ago today’s findings are a major update, confirming and extending the cohesive properties of head-direction cell networks.
