The Lick

There’s a certain jazz lick that’s so heavily used that it’s just known as The Lick. It’s the only jazz lick I know of that has its own Facebook page. Here’s a greatest hits compilation:

Why do I grimace when I concentrate?

The parts of your brain that do your abstract thinking are very tightly interconnected with the parts that control your muscles. In fact, some of that abstract thinking is done by the same brain regions that control your muscles. We don’t yet know why a specific brain region produces a given specific thought, but the [...]

The Makossa diaspora

The first time I heard Manu Dibango’s “Soul Makossa” was courtesy of Motorcycle Guy, a prominent Brooklyn eccentric who drives around on a tricked-out motorcycle bedecked with lights and equipped with a powerful sound system. I encounter him every so often and he’s always bumping some good funk, soul or R&B. One night, he was [...]

What is the evolutionary purpose of dreaming?

Dreaming doesn’t have an evolutionary purpose per se. It’s just an emergent property of the piecemeal way our brains have evolved, from the older and more automatic systems out to the newer, learning-enabled systems. I’ve seen it suggested by several different scientists that most animals go about their waking lives in a state similar to [...]

Why has the human brain evolved so much more than any other animals?

The human brain isn’t “more” evolved. It’s just differently evolved. Our intelligence has its obvious advantages, but it carries some significant costs. Like Joshua Engel says, the big brain is metabolically expensive. It makes childbirth much harder for humans than for other mammals, too. Human babies have to be effectively born prematurely in order to [...]

Does teaching Intelligent Design in schools really damage science?

You don’t go to high school biology class to learn particular facts; you go to understand the general framework of evolutionary theory. Rather than contradicting any single fact, Intelligent Design undermines the entire intellectual basis of biology.

Is Richard Dawkins helping science through his attacks on religion?

I would wish for Dawkins to use more emotional sensitivity and compassion when dealing with religious people, because his hostile tone gets in the way of his invaluable message. His condescending attitude toward believers, epitomized by calling atheists “brights,” is seriously counterproductive. I’m concerned that he’s unnecessarily confrontational and inflammatory in his TV appearances, op-eds [...]

Why does listening to music sometimes make you feel high?

I’ve been lucky enough to experience heightened and altered consciousness from music making, listening and dancing. Chasing that feeling motivates me to keep making and studying music, in spite of the lousy pay. I’m reading a wonderful book right now by William Benzon called Beethoven’s Anvil. Benzon looks at the state of brain research and [...]

What goes on neurologically when a song gets stuck in your head?

The phenomenon of annoyingly persistent earworms is a great introduction to the meme theory: the idea that songs (and all other forms of cultural expression) are self-replicating informational “viruses” that use the mind as their host, the way DNA viruses use living cells and software viruses use computers. The best overview of this theory is [...]

Samples and community

The defining musical experience of my lifetime is hearing familiar samples in unfamiliar contexts. For me, the experience is usually a thrill. For a lot of people, the experience makes them angry. Using recognizable samples necessarily means having an emotional conversation with everyone who already has an attachment to the original recording. Music is about [...]
