Photoreceptors and Plant Responses to Light

Photoreceptors and Plant Responses to Light

Light plays a significant role in regulating the growth and development of plants. In addition to providing energy for photosynthesis, light provides other important cues to regulate a range of developmental and physiological responses in plants.

Photoelectric Effect

Photoelectric Effect

When light of a particular wavelength strikes a metal surface, electrons are emitted. This is called the photoelectric effect. The minimum frequency of light that can cause such emission of electrons is called the threshold frequency, which is specific to the metal. Light with a frequency lower than the threshold frequency, even if it is of high intensity, cannot initiate the emission of electrons. However, when the frequency is higher than the threshold value, the number of electrons ejected...

The Photochemical Reaction Center

The Photochemical Reaction Center

Reaction centers are pigment-protein complexes that initiate energy conversion from photons to chemical entities. Therefore, photochemical reaction center is a more appropriate term that describes these complexes. The Nobel laureates Robert Emerson and William Arnold provided the first experimental evidence of photochemical reaction centers by demonstrating the participation of nearly 2,500 chlorophyll molecules for the release of just one molecule of oxygen. Despite thousands of photosynthetic...

Total Internal Reflection Fluorescence Microscopy

Total Internal Reflection Fluorescence Microscopy

Total internal reflection fluorescence microscopy or TIRF is an advanced microscopic technique used to visualize fluorophores in samples close to a solid surface with a higher refractive index, such as a glass coverslip. TIRF only allows fluorophores in proximity to the solid surface to be excited. When light from a medium with a lower refractive index (such as air) hits the glass coverslip at a critical angle, the light undergoes total internal reflection stead of passing through the glass.

Radiation: Applications

Radiation: Applications

The average temperature of Earth is the subject of much current discussion. Earth is in radiative contact with both the Sun and dark space; it receives almost all its energy from the radiation of the Sun and reflects some of it into outer space. Dark space is very cold, about 3 K, so Earth radiates energy into it. For instance, heat transfer occurs from soil and grasses, the rate of which can be so rapid that frost can occur on clear summer evenings, even in warm latitudes.
The average...

Photoreceptors and Visual Pathways

Photoreceptors and Visual Pathways

At the molecular level, visual signals trigger transformations in photopigment molecules, resulting in changes in the photoreceptor cell's membrane potential. The photon's energy level is denoted by its wavelength, with each specific wavelength of visible light associated with a distinct color. The spectral range of visible light, classified as electromagnetic radiation, spans from 380 to 720 nm. Electromagnetic radiation wavelengths exceeding 720 nm fall under the infrared category, whereas...

Comparative Neuroscience
Neuroimaging
Primate Brain Research

Background:

Neuroscience commonly uses macaque models to understand human brain function.
Identifying homologous brain regions across species and measurement types, especially in higher-order cortex, is challenging due to non-homologous anatomy and narrow hypotheses.

Purpose of the Study:

To develop and validate a data-driven approach for mapping functional correspondence between macaque and human brains.
To overcome limitations of traditional methods relying on predefined concepts and limited stimuli.

Main Methods:

Directly compared macaque electrophysiology with human functional Magnetic Resonance Imaging (fMRI) data.
Utilized responses to 700 natural scenes as stimuli, focusing on response pattern similarity for alignment.
Applied the method to the ventral face patch system as a test case.

Main Results:

Achieved fine-grained functional alignment between macaque and human brain regions based on natural scene response patterns.
The identified correspondence aligns with full-brain anatomical warping.
Results contradict previous findings limited by narrow functional hypotheses.

Conclusions:

Natural image-evoked response patterns offer a robust basis for cross-species functional alignment in neuroscience.
This approach supports scalable comparisons as large-scale primate recordings increase.
Resolves ambiguities in cross-species brain region mapping, particularly in visual processing areas.
