2. The AAV capsid variant of claim 1 , wherein the amino acid sequence of SPHSKA (SEQ ID NO: 941) is present immediately subsequent to amino acid 455, numbered according to SEQ ID NO: 981.

3. The AAV capsid variant of claim 1 , which comprises an amino acid sequence at least 98% identical to amino acids 203-742 of SEQ ID NO: 981.

4. The AAV capsid variant of claim 1 , which comprises the amino acid sequence of amino acids 203-742 of SEQ ID NO: 981.

5. An AAV particle comprising the AAV capsid variant of claim 4 .

6. A pharmaceutical composition comprising an AAV particle comprising the AAV capsid variant of claim 4 , and a pharmaceutically acceptable excipient.

7. The AAV capsid variant of claim 1 , which comprises an amino acid sequence at least 95% identical to amino acids 138-742 of SEQ ID NO: 981.

8. The AAV capsid variant of claim 1 , which comprises an amino acid sequence at least 98% identical to amino acids 138-742 of SEQ ID NO: 981.

9. The AAV capsid variant of claim 1 , which comprises the amino acid sequence of amino acids 138-742 of SEQ ID NO: 981.

10. The AAV capsid variant of claim 1 , which comprises an amino acid sequence at least 95% identical to the amino acid sequence of SEQ ID NO: 981.

11. The AAV capsid variant of claim 1 , which comprises an amino acid sequence at least 98% identical to the amino acid sequence of SEQ ID NO: 981.

12. A cell comprising the AAV capsid variant of claim 1 .

13. The cell of claim 12 , which is:

(i) a mammalian cell or an insect cell;

(ii) a cell of a brain region or a spinal cord region; or

(iii) a neuron or an astrocyte.

14. A pharmaceutical composition comprising an AAV particle comprising the AAV capsid variant of claim 1 , and a pharmaceutically acceptable excipient.

15. A method of making an AAV particle, comprising:

(i) providing a host cell comprising a viral genome and a polynucleotide encoding the AAV capsid variant of claim 1 ; and

(ii) incubating the host cell under conditions suitable to enclose the viral genome in the AAV capsid variant;

thereby making the AAV particle.

16. A method of delivering a payload to a cell or tissue, comprising administering an effective amount of an AAV particle comprising the AAV capsid variant of claim 1 , thereby delivering the payload to the cell or tissue.

17. The method of claim 16 , wherein the cell or tissue is present in a subject and the AAV particle is administered intravenously, via intra-cisterna magna injection (ICM), intracerebrally, intrathecally, intracerebroventricularly, via intraparenchymal administration, or intramuscularly to the subject.

18. The method of claim 16 , wherein:

(i) the cell is a neuron, a motor neuron, an astrocyte, a glial cell, or an oligodendrocyte; or

(ii) the tissue is a brain tissue or a spinal cord tissue, wherein the brain tissue or the spinal cord tissue is a putamen, substantia nigra, frontal cortex, motor cortex, temporal cortex, caudate, dentate nucleus, brain stem, cerebral cortex, brain stem, hippocampus, thalamus, cervical spinal cord, thoracic spinal cord, or lumbar spinal cord.

19. An adeno-associated virus (AAV) capsid variant comprising the amino acid sequence of SEQ ID NO: 981.

20. An AAV particle comprising the AAV capsid variant of claim 19 .

21. A pharmaceutical composition comprising an AAV particle comprising the AAV capsid variant of claim 19 , and a pharmaceutically acceptable excipient.
