Activating the indicator and performing a shoulder check – essential also for zebra finches
Zebra finches in flight in a wind tunnel. The birds use both vision and calls to coordinate their flight positions and avoid collisions.
Messenger RNAs use mitochondria as a vehicle to reach distant locations within nerve cells. There, they can be used as blueprints for the production of short-lived proteins that would not survive the long journey. Research from the group of Angelika Harbauer.
Electrical synapses connect neurons in almost all brains; however, little is known about them. A study now shows for the first time where these specific synapses occur in the fruit fly brain and that they influence the function and stability of nerve cells. Research from the department of Alexander Borst.
Zebra finch males sing in dialects and females pay attention
Using an artificial intelligence technique, researchers discovered dialects in the songs of different zebra finch populations. A small backpack including a QR code was used to track all individuals and create social interaction maps. The researchers found that females select their partner mainly according to dialect. Research from the department of Bart Kempenaers.
Ruffs males come in three different morphs. Independents (in the back) aggressively defend a territory to impress females. Satellites (right) build alliances with Independents, while the rare Faeder males (front) look and behave like females to avoid aggressive competition with other ruff males. Research from the group of Clemens Küpper.
Asymmetry as a building block of neuronal computations
Structure and function of neurons are closely linked in the cerebral cortex. Pyramidal cells in mouse visual cortex respond selectively to the orientation and direction of objects. Research from the department of Tobias Bonhoeffer.
