When trying to model how behaviors and traits evolved, it helps to keep things simple — but the problem with friendship is that it involves a
number of complex behaviors.
However, it is clear from recent literature that the cognitive abilities of fish have been greatly underestimated and that teleosts are
capable of complex behaviors such as individual recognition, transmission of cultural traditions, cooperation, copying behavior and deception, which have traditionally been associated with the evolution of large cortical areas in mammals and birds [69], [70].
More recently, I have demonstrated the feasibility of using fMRI in combination with pharmaco - genetic silencing to dissect the circuital
basis of complex behaviors, and demonstrated for the first time that the mouse brain contains distributed resting - state functional connectivity networks, including plausible homologues of the human default - mode (DMN) and salience networks.
To demonstrate the
kind of complex behaviors that can be achieved with simple commands, Becker videotaped an experiment over the Labor Day weekend in which a swarm of a dozen randomly scattered r - one robots were directed to form a complex shape — a capital R. To direct the robots, Becker used a basic controller — a simple one - button,»80s - era videogame joystick that was capable of giving only two commands: rotate and roll forward.
«The identification of genes regulating sleep - feeding interactions will provide important insight into how the brain integrates and controls the
expression of complex behaviors,» said Keene.
Studies of courtship and mating in the fruit flyoffer a window on the ways genes influence the execution of complex behaviors
Why It Matters: Quantification of forces between crystal faces enables
predictions of complex behaviors in colloidal systems such as self - assembly, aggregation, and rheological properties of slurries.
Whereas previous scales have measured only a subset of feeding practices, the 12 subscales of the CFPQ allow researchers and clinicians to measure many
aspects of this complex behavior.
Instead it is a molecule that — even on its own — «is
capable of complex behavior,» says senior author David Soloveichik, an electrical and computer engineer at the University of Texas at Austin.
We address these questions by studying an animal that is capable
of complex behavior and yet simple enough to allow systematic genetic manipulation of all parts of the neural circuitry.
