Locomotion Control of Pigeons using Polymer-based Deep Brain Electrodes.
Summary
Researchers electrically stimulated pigeons' brains to control locomotion. Deep brain electrodes induced taking-off behavior, paving the way for remote flight-control systems.
Area of Science:
- Neuroscience
- Bioengineering
- Animal Behavior
Background:
- Locomotion control in animals is complex.
- Electrical stimulation offers a potential method for modulating animal movement.
Purpose of the Study:
- To investigate the electrical modulation of pigeon locomotion.
- To explore the induction of taking-off behavior via brain stimulation.
Main Methods:
- Fabrication of four-channel, polymer-based depth electrodes.
- Implantation of electrodes into the nucleus intercollicularis (ICo) region of pigeon brains.
- Delivery of biphasic current pulses (0.5 mA, 58.0 Hz, 320 µs) to stimulate the ICo.
Main Results:
- Successful induction of taking-off behavior in pigeons through electrical stimulation of the ICo.
- Induced taking-off behavior lasted for 0.4 seconds.
- Stimulation parameters: 0.5 mA amplitude, 58.0 Hz rate, 320 µs duration, applied for 0.5 s.
Conclusions:
- Electrical stimulation of the nucleus intercollicularis can reliably induce taking-off behavior in pigeons.
- This method holds potential for developing remote flight-control systems for freely moving pigeons.
- Coupling stimulation with control of turning and forward locomotion could enable advanced avian robotics.

The word polymer is derived from the Greek words “poly” which means “many” and “mer” which means “parts”. Polymers are long chains of molecules composed of repeating units of smaller molecules, known as monomers. They either occur naturally, such as DNA and proteins, or can be constructed synthetically, like plastics. They have varied structural characteristics, such as linear chains, branched chains, or complex networks, that contribute to the...

On comparing the reactivity of silver and lead, it is observed that the two ionic species, Ag+ (aq) and Pb2+ (aq), show a difference in their redox reactivity towards copper: the silver ion undergoes spontaneous reduction, while the lead ion does not. This relative redox activity can be easily quantified in electrochemical cells by a property called cell potential. This property is commonly known as cell voltage in electrochemistry, and it is a measure of the energy which accompanies the charge...

Electrochemical measurements are conducted in an electrochemical cell composed of various components that control and measure the current and potential. One fundamental component is electrodes, conductive materials that enable electron transfer reactions at their surfaces.
There are two main types of electrodes in electrochemical cells. The first type, known as the working or indicator electrode, has a potential that is sensitive to the analyte's concentration and reacts to changes in...

Polymers are classified as linear or branched on the basis of their chain architecture. The polymer chains in linear polymers have a long chain-like structure with minimal to no branching at all. Even if a polymer features large substituent groups on the monomer, which appear as branches to the skeleton, it is not considered a branched polymer. A branched polymer contains secondary polymer chains that arise from the main polymer chain. The branching occurs when the polymer growth shifts from...

Unlike ionic or small covalent molecules, polymers do not form crystalline solids due to the diffusion limitations of their long-chain structures. However, polymers contain microscopic crystalline domains separated by amorphous domains.
Crystalline domains are the regions where polymer chains are aligned in an orderly manner and held together in proximity by intermolecular forces. For example, chains in the crystalline domains of polyethylene and nylon are bound together by van der Waals...
