Visualization of Thalamocortical Axon Branching and Synapse Formation in Organotypic Cocultures06:16

Visualization of Thalamocortical Axon Branching and Synapse Formation in Organotypic Cocultures

6.9K
This protocol describes a method for simultaneous imaging of thalamocortical axon branching and synapse formation in organotypic cocultures of the thalamus and cerebral cortex. Individual thalamocortical axons and their presynaptic terminals are visualized by a single cell electroporation technique with DsRed and GFP-tagged...

Preparation of Colliculo-Thalamocortical Slices from a Mouse Pup Brain

461
The video demonstrates the preparation of colliculo-thalamocortical brain slices from mouse pup brains. An isolated brain is aligned on a marked slide and cut at an angle to align the auditory midbrain and forebrain in the same plane. The brain is then sliced using a vibratome, and the slices containing the major auditory midbrain and forebrain structures are transferred to a holding chamber for...

Using SCOPE to Identify Potential Regulatory Motifs in Coregulated Genes

10.7K
A straight-forward and robust method to identify potential regulatory motifs in co-regulated genes is presented. SCOPE does not require any user parameters and returns motifs that represent excellent candidates for regulatory signals. The identification of such regulatory signals helps to understand the underlying...

Peptide-based Identification of Functional Motifs and their Binding Partners

13.0K
Techniques to dissect the mechanisms underlying the secretion of HIV-1 Nef in exosomes are described. Specific short peptides derived from Nef and protein transfection were exploited to determine the structure, function, and binding partners of Nef’s Secretion Modification Region. These procedures have general relevance in many mechanistic...

Second-Order Circuits01:17

Second-Order Circuits

3.3K
Integrating two fundamental energy storage elements in electrical circuits results in second-order circuits, encompassing RLC circuits and circuits with dual capacitors or inductors (RC and RL circuits). Second-order circuits are identified by second-order differential equations that link input and output signals.
Input signals typically originate from voltage or current sources, with the output often representing voltage across the capacitor and/or current through the inductor. For example, in...

Synthesis and Characterization of Functionalized Metal-organic Frameworks11:27

Synthesis and Characterization of Functionalized Metal-organic Frameworks

49.1K
Synthesis, activation, and characterization of intentionally designed metal-organic framework materials is challenging, especially when building blocks are incompatible or unwanted polymorphs are thermodynamically favored over desired forms. We describe how applications of solvent-assisted linker exchange, powder X-ray diffraction in capillaries and activation via supercritical CO2 drying, can address some of these...

Area of Science:

  • Neuroscience
  • Computational Neuroscience
  • Systems Neuroscience

Background:

  • The thalamus's role in sensory transmission is established, but its broader cognitive functions are underappreciated.
  • Recent research indicates thalamic involvement in attention, executive control, and decision-making.
  • The circuit mechanisms driving these cognitive roles remain largely unknown.

Purpose of the Study:

  • To highlight the necessity of understanding thalamic circuit mechanisms for cognitive functions.
  • To propose a new classification framework for thalamic organization based on thalamocortical motifs.
  • To emphasize the importance of thalamic organization in systems and computational neuroscience.

Main Methods:

  • Discussion of existing thalamic organizational schemes (core/matrix, first-order/higher-order).
  • Analysis of thalamic neuron connectivity patterns.
  • Synthesis of current research on thalamic function in cognition.

Main Results:

  • Thalamic engagement in dynamic regulation of cortical activity is evident in attention, executive control, and perceptual decision-making.
  • The lack of local recurrent excitatory connectivity in the thalamus necessitates detailed mapping of long-range connections.
  • Existing classification schemes may not fully capture functional organization.

Conclusions:

  • A new classification based on thalamocortical motifs is proposed to better link structure and function.
  • Understanding thalamic organization is critical for advancing systems and computational neuroscience.
  • This research has implications for both basic neuroscience and translational applications.
