| Transversal semi-thin section of a juvenile amphyoxus (B. lanceolatum) |
 |
| Amphioxus are fish-like marine chordates which are particularly interesting to study the evolution of vertebrates. A post-metamorphic juvenile is seen here in transverse section. Notice the nervous cord as the large round structure in the centre of the animal. Methylene blue stain was used in this preparation. |
| Double Immunofluorescence in stratum lucunosum moleculare |
 |
| Immunoflourescence of two proteins found in excitatory synapses: vesicular glutamate transporter 1 (VGluT1) and glutamate receptor 1 (GluR-1). VGluT1, labelled in red, is a marker of presynaptic buttons while GluR-1, in green, marks postsynaptic terminals. Image taken from mouse stratum lacunosum moleculare, a layer of the hippocampus. |
| Triple staining of hippocampus from mouse (Mus musculus) |
 |
| Mouse hippocampal formation labelled fluorescently. Nuclei are labelled in blue with DAPI and excitatory synapses in green and red with antibodies against glutamate receptor 1 (GluR-1) and vesicular glutamate transporter 1 (VGluT1) respectively. |
| Electron mycrographs of synapses from zebrafish brain |
   |
| Mycrographs of glutamatergic synapses from the optic tectum of the zebrafish (Danio rerio) brain. The postsynaptic element presents a characteristic electron-dense structure named postsynaptic density, which is a large protein complex containing glutamate receptors and signalling molecules regulating synaptic activity and plasticity. |
| Graphical representation of main functional classes amongst postsynaptic proteins |
 |
| Proteins found in the postsynaptic density can be classified according to their molecular function. This diagram represents the landscape of molecular functions found amongst postsynaptic proteins. Bar length corresponds with the number of proteins found in each functional group. Colour intensity corresponds with functional class overrepresentation level as compared with the human genome. |
| Modernist building of the Hospital de la Santa Creu i Sant Pau. |
 |
| Our institute is part of the Hospital de la Santa Creu i Sant Pau. The buildings were the hospital used to be were build in modernist style early in the XX century by the architect Lluís Domenech i Muntaner. The modernist hospital was declared world heritage site by the UNESCO in 1997. Learn more. |
